I have a UK Voda contract which includes charge-free roaming to EU, US

never had any issues with multi-month absences (longest 16mo during

Objective data gathering, as well as subjective discussions, is also good.

I suspect people are kind of burned out looking at pandemic-inflected
traffic graphs by now, but perhaps further into 2021 some analysis of
traffic/routing data over the Brexit transition window might be
interesting, and generate an insightful presentation or two.

It's seemed to me for a long time that the culture of British employers
spending resources on the professional development of their IT
operations people has been sadly lacking compared to world-class best
practice, and also feels like this is getting worse :-( We've always
tried to bridge that gap at UKNOF by bringing in international speakers,
seems like there are some challenges to come to keep this going..

This is a separate invite to sign up for the chat server, for meeting
remote participation, that was sent to everyone who registered for the
July virtualUKNOF, in addition to the general chat server invite in my
announcement here yesterday. Apologies for the duplication, but not
everyone who registers for events is on this list.

No, the mailman mailing list, indico events platform, and mattermost
chat server are all completely separate, whatever e-mail address you use
for one will have no impact on the others.

[uknof] A new community chat platform for UKNOF

[Keith Mitchell]

UKNOF is here to help our community of network engineers run their
operations more smoothly. A tool that's often useful for both
infrastructure operations and remote participation at industry events is
a real-time chat platform.

This has been provided on a somewhat ad-hoc basis during UKNOF's 15-year
history, mainly over IRC using the #uknof channel on terahertz.net.

While IRC has its place (& will probably never die :-), it's also clear
there are *many* modern alternatives. We wanted to serve the community
better with one of these, and in a way which would be inclusive and
appealing to more than just IRC die-hards.

A new chat platform is also timely for our pandemic age:

- to better enable remote participation at virtualUKNOF meetings
- to help co-ordinate operations while the Internet's infrastructure
  is under unique pressures
- co-ordination of UKNOF volunteers
- to provide a community gathering place

After some internal review, we decided this would be best provided using
the Mattermost chat platform, which has many modern features like mobile
app, encryption, and rich media support; is based on a cross-platform
open-source code base; and does not lock us into any single provider.

The new Mattermost server, <https://chat.uknof.org.uk> was tested out by
the UKNOF meetings Crew for internal co-ordination during the May
virtualUKNOF, and it worked very well.

We would thus like to open up this service to the entire UKNOF
community, you can sign up for a Public account here:


https://chat.uknof.org.uk/signup_user_complete/?id=jinormi7y3869884s5ri96sgfc

and find various client apps here:

https://mattermost.com/download/

A REMINDER that the UKNOF Respect Policy:

https://uknof.uk/respect

applies every bit as much to our Mattermost (& IRC) chat as everything
else that UKNOF does online and offline, and you are bound to this by
signing up to any of our activities or platforms.

We realise there are *many* chat platforms out there, and we're never
going to please everybody whichever is chosen, but believe it's better
to provide something that's going to be the best and most cost-effective
use to the most people. The IRCers among you will have also noticed that
we have as a temporary migration measure bridged between #uknof and the
"UKNOF" Channel on Mattermost.

If you need help getting up and running, please contact
.

Our Mattermost server is being operated by the same UK-based provider
that operates UKNOF's other cloud infrastructure, Mythic Beasts, and you
can expect the same high standards of engineering and privacy from them
that you have for other UKNOF services. Like most UKNOF activities, this
service is funded for open community public benefit by our Patrons,
Sponsors, Friends and event attendees. We hope you will find it useful,
and find a way to join them in supporting this and our other activities
at UKNOF.

submissions, so as to ensure the quality of the workshop, submissions
SHOULD include slides. Draft slides are acceptable on submission.

Additional information for speakers of OARConline 32b:

  * your talk will be broadcast live and recorded for future reference

Re: [uknof] internet infrastructure interviews with experts

[Keith Mitchell]

Memhet,

Not for the first time this week, I find myself having to respond to a
complaint made about your posting below on one of the nonprofit public
benefit Internet operations mailing lists I am responsible for.

I will draw your attention to the UKNOF Charter:

https://wiki.uknof.org.uk/Charter

* UKNOF's mailing lists may not be used for promotion of
  commercial activities or products.

At this point it remains unclear if your activity below is commercial or
not. I suggest that if people in more than one place feel it necessary
to file complaints about your postings, you need to do more to either
clarify that or respect the lists' charter.

Re: [uknof] Reminder: UKNOF respect policy

[Keith Mitchell]

And we are living in extraordinary times, when going the extra mile
beyond basic professional respect and courtesy counts for a lot.

Taking a bit of a meta step back from on-topic:

I've seen a few articles along the following lines recently, looking
into the research psychology of long-term isolation on people, here's a
couple for instance:


https://www.abc.net.au/triplej/programs/hack/coronavirus-covid19-isolation-third-quarter-phenomenon-has-begun/12190270

https://www.ft.com/content/eb056344-9b80-11ea-871bedeb99a20c6e  
(paywalled)

I don't think anyone really knows how far into this we are or have to go
exactly, but much of this research is still relevant. TL;DR: "people get
weirdest from isolation when they get past the perceived half-way mark".

This is a difficult time for many, and if we could as a community all be
that bit more mindful of others, our own mental state, and of the
shortcomings of online interaction not mitigated by F2F gathering,
/before/ we hit the "F-key", I think it would serve us well.

Thank you to everyone keeping the discussion civil and (returning you
to..) on-topic.

Keith

Re: [uknof] 9pm data dip

[Keith Mitchell]

Could it simply be people switching to/from some popular nightly item on
linear broadcast TV from/to whatever streaming they were consuming ?
Noting the "Coronation Street kettle" effect of years gone by, if the
power utilities publish real-time consumption stats with enough time
resolution that may also be interesting to examine.

Having a look at what DNS queries are being sent to ISP resolvers around
that time may also yield insights.

It would be even better if one of those did not blow an important
advantage of IPv6 by giving their end-users non-dynamic address assignments.

The approach of the largest ISPs in the US towards IPv6 is kinda
curious, which seems to be to offer it as standard, but to not actually
provide any documentation on the availability, service or CPE equipment,
you have to figure it all out. Once I'm done figuring how to get *both*
my ISPs to consistently do prefix delegation, my IPv6 universe will be a
much happier one...

See that too, I've long regarded 185.40... as toxic swampy neigbourhood

The UKNOF Charter says:

"UKNOF's mailing lists may not be used for promotion of commercial

so posting of jobs ad for commercial entities is probably stretching
that a bit. I don't think anyone wants to see this list swamped with job

It's great to see work being done to better understand the perennial
problem of IP address spoofing.

Another research group working on this problem (via measurement) is the
Spoofer project, which was taken over by CAIDA in 2015. Something I
thought would be of interest to a UKNOF audience is the per-country
breakdown of which providers are allowing spoofed packets to leak out of
their infrastructure:

Seems like overall UK source-address-verification health is good, though
with a couple of AS blackspots.

I'm not suggesting it's necessary in this particular case, but it's also
worth mentioning in case some folks are not aware, that the RIPE NCC has
an Arbitration Panel (which I serve on) and Process:

https://www.ripe.net/about-us/legal/arbitration

which is available for escalating disputes which cannot otherwise be
resolved between NCC members and/or the NCC itself. IME, as and Nigel
says, a lot of these things boil down to misunderstandings across
language/culture/jurisdiction/policy barriers.

Things may very well have moved on since I proposed this, but I think at
the time a very large proportion of LIRs were UK-based, so subscribing
to a few of the larger national company registries could potentially
have covered a significant share of the NCC's remit. Of course, from a
policy point of view it might well be necessary to subscribe to them all
so as not to be seen to discriminate against particular countries, and
indeed that could get gnarly.

Re: [uknof] Tracking BT MCT progress for VDSL hardware

[Keith Mitchell]

I'm slightly astonished that we're in this situation in 2016. My old
fart memory goes back as far as the mid 1980s, when BT had just been
privatised out of the Post Office, and people were trying to move beyond
their 300/1200 acoustic coupler modems on phones hard-wired into the
wall. The approval bar very high for what 3rd-party equipment
(even phone handsets !) could be connected to their new-fangled jack
sockets, and many similar accusations of test delays, expensive tests,
potential conflicts of interest, anti-competitiveness etc were being
bandied around.

The solution at the time was that approval testing was spun out into an
independent 3rd party, BABT (* British Approvals Board for
Telecommunications). AFIACT it appeared to resolve the situation very
well. I don't know exactly what BABT does now, but feels like a
similar solution is called for these days...

To be clear, while we are having a session at UKNOF33 which will attempt
to shed light on the potential _operational_ impact of the IPBill, UKNOF
does not take public policy positions. Any UKNOF participants who give
evidence will be doing so in their own right, and not in the position of

Indeed, in the absence of detailed public statements, analyzable data
would be a good thing. What's baffling me about these attacks is the
motivation - it's very much the season for online shopping extortion
attacks, and what happened to the root last week suggests there's a lot
of DDoS generally going on right now, but its not clear what's to be
gained from taking out academic infrastructure. I hope it's not some
deadline-shy undergrad using a booter site to avoid their assessments
("the DoS ate my homework"...), but sadly such things are not
inconceivable these days.

Thanks Neil, the UKNOF33 agenda is nearly full, but that could indeed be

As per Nat's announcement on the 1st September, the archives are no

There is a chicken and egg relationship between Internet Exchange

supports it, that it in turn supports. If one expects the
introduction of one to solve the lack of the other, it is doomed to
fail. Been there, seen that, multiple times.

Community building is not something you can do in months, or even a
year, it requires a long-haul commitment, with a longer cycle than is
generally consistently deliverable from public servants of various flavours.

This is no longer the 1990s where the density of IXPs per country was

October 13th there will be a joint session with ICANN Tech Day. OARC is
requesting proposals for presentations, with a preference for DNS data
analysis tools and techniques.

This workshop continues OARC's tradition of having meetings include a
strong operational component. Presentations from DNS operators are
particularly welcome.  We'll also gladly accept talks from DNS
researchers, as well as any other DNS-related subjects such as tools,
visualizations, DNSSEC and novel uses of the DNS. Adopting practice
from other conferences, a section of lighting talks will be available
for short presentations.

Workshop Milestones
* 20 July 2014, Call for Presentations posted
* 21 July 2014, Open for submissions
* 15 August 2014, Deadline for submission
* 29 August 2014, Final Program published

Details for abstract submission will be published here:

https://indico.dns-oarc.net/event/workshop-2014-10

The workshop will be organized on different tracks, depending on the
topics. On Sunday October 12th we will have the more in depth technical
presentations, and on Monday October 13th presentations that can benefit
from a larger and broader audience. If you consider submitting a
presentation, please let the Programme Committee know for which track in
advance to help us organize the presentations tracks. You can contact

 devastating DoS to be launched against anyone anywhere.
 
 Indeed - which is certainly a problem! :)
 
 So what's the 'proper' solution to all this then beyond just adding 
 enough capacity to absorb ever larger attacks? How's this going to 
 end up?

What's happening now is that reactive, specific measures are being taken
- protocol-specific vulnerabilities (e.g. RRL for DNS, disable monlist
for NTP) are being plugged, ISPs are deploying better instrumentation to
detect attack flows, and are turning on uRPF/other source-address
filtering towards the worst traffic sources.

The problem with these approaches is that:
- they are just going to lead to an endless game of whack-a-mole as the
  bad guys find ever more reflection vectors which need plugging
- this arms race will in turn educate the bad guys to be smarter
- the vendors of security products are going to be more interested in
  selling bigger faster $olutions than tackling the underlying problems
  (cf ever-increasing claims for how big an attack various vendors
   claim to have dealt with)
- TPTB are more likely to blame the Internet industry and take
  regulatory measures against us as an easy target than tackle the
  actual bad guys

Something I think that would make a bigger difference would be for data
to be gathered and published that names-and-shames those providers that
don't do BCP38 source address validation. As an industry we then need to
start contractually enforcing, de-peering and blocking traffic to/from
those providers who don't take action to remedy this.

The other thing is to beat up on our vendors - I hear many stories of
how BCP38 cannot be implemented by people who want to, due to some bug
or missing feature with CPE/edge/aggregation/core equipment.

If self-regulation doesn't work, we can expect regulation. While
mandating SAV/BCP38 would IMHO be a much more useful single item of
legislation to reduce Internet evil than the swathes of vested-interest
pandering nonsense we've had from our governments and regulators lately,
it's hard to trust them to do it right.

In any case, there are also many (probably most) nation-states out there
proudly declaring that they have cyberwarfare capability, and it's
hard to see how this is credible without a DDoS element. It might
actually take international Internet disarmament treaties to nail this
problem :-(

[uknof] Call for Presentations - DNS-OARC Spring Workshop, May 2014

[Keith Mitchell]

Call for Presentations - DNS-OARC Spring Workshop, May 2014

The next OARC Spring Workshop will take place in Warsaw, Poland on May
10th and 11th, the weekend before RIPE68. OARC is requesting proposals
for presentations, with a preference for DNS privacy and confidentiality
work and ideas, and DNS over alternative (non UDP) transports.

This workshop continues OARC's tradition of having meetings include a
strong operational component. Presentations from DNS operators are
particularly welcome.  We'll also gladly accept talks from DNS
researchers, as well as any other DNS-related subjects such as tools,
visualizations and data analysis.  If you are an OARC member, and have a
sensitive topic you would like to present for members-only, we will
accommodate those talks too. Adopting practice from other conferences, a
section of lightning talks will be added for short presentations.

Workshop Milestones
*  6 January 2014, Open for submissions
*  1 March 2014, Deadline for submission
* 28 March 2014, Final Program published
*  9 May 2014, Final deadline for slideset submission

Details for abstract submission are available here:

I'm going to refer you to UKNOF's charter
(http://www.uknof.org.uk/charter.html):

UKNOF's remit is technical, and any discussion or activities
 involving  commercial, legal or political issues should be limited to
 where they have a direct impact on technical aspects of network
 operations.

We don't as an organisation take public policy positions, so signing
position statements is just not something UKNOF does. That doesn't mean
we can't discuss and share information about public policy proposals,
legislation and regulations where they are going to have a direct impact
on running the UK's network infrastructure.

 Or maybe some of you would like to recommend it to your own 
 organisations:

There's plenty of other organisations around that exist primarily to
engage in forming public policy, UKNOF participants are of course free
to support these, and lobby them to adopt positions, in their own right
as they see fit.

And UKNOF is of course about open sharing of information, so thank you
for giving everyone a heads-up on the above.

Hope that clarifies.

Sorry about this - I agree the wording on the registration page is

 Sounded like it was what I wanted, but when I followed through I could not see
 it as registration. Looked like donation only.

If you click on register on the Eventbrite paid registration page, it
will take you to a registration form. We haven't yet managed to
integrate the main free Indico registration system with the

 And bring a bucket to the meeting so we can donate if we want to.

[uknof] UKNOF25 Final Information

[Keith Mitchell]

Here's a few final pieces of information for those attending UKNOF25:

We have a packed agenda for tomorrow, and I'm excited about the large
number of high quality talks we have lined up. In the morning our major
theme is about new wireless technology, with our Platinum sponsor
talking about LTE deployment in practice, followed by updates on UK
wireless spectrum and whitespace networks.

Following recent events in the SpamHaus vs StopHaus DDoS wars, there's
a highly topical talk on the importance of BCP38 IP filtering deployment.

In the afternoon, we're looking at new developments in fibre, including
urban and rural local loops, and an update from Greg Hankins of Brocade
on 100Gb/s Ethernet.

I'm pleased to welcome Mike Kelly, the founder of TeleCity, for our
first UK Internet History presentation in a while. He'll be talking
about the history of early Internet Exchange activities in Manchester
and his co-location startup experiences. Looking forwards, we have an
update on recent IXP developments in Scotland.

We also have an problem solved update follow-up talk from his UKNOF21
presentation on BufferBloam from Dave Taht, and talks on video codecs
and BGP.

You can find the agenda for the meeting at:

http://indico.uknof.org.uk/conferenceDisplay.py?confId=27

and the slide decks will be available linked from this page.


We are not aware of any specific restrictions on access to our social or
meeting venues due to the Thatcher funeral, however given this and other
recent developments and upcoming events, it seems reasonable to assume
there will be some degree of travel disruption and heightened security
in central London, so please build a little extra time and patience into
your schedule.


UKNOF25 kicks off this evening at 7:30 for 8pm with the traditional
pre-meeting Curry Social, sponsored by IXReach. If you indicated
interest in this, you should have heard from, and additionally RSVPed
to, elaine.di...@ixreach.com, from whom you should now have received
venue details.

Although all our free sponsored places are filled, we still have room
for more attendees on a paying basis - you can still register for the
meeting or at the door via:

http://uknof25.eventbrite.co.uk

As usual, and for those of you who are not able to attend, we will be
webcasting the event, at:

http://uknof.bogons.net/uknof25.html

with thanks to Bogons and Portfast.

Remote participation is supported by the IRC channel:

At the end of the day's proceedings (6pm) there will be social drinks,
sponsored by hardware.com, you can find out _where_ by attending during
the day :-) We have another 25th meeting surprise lined up too !

Finally, a big thank you to Ericsson for being our first Platinum

[uknof] UKNOF25 Agenda and Late Registration available

[Keith Mitchell]

I'm pleased to announce that the agenda for UKNOF25 is now available at:

http://indico.uknof.org.uk/conferenceOtherViews.py?view=standardconfId=27

UKNOF25 will take place at 15Hatfields, Southwark, London
on Thu 18th April.

Our Platinum meeting sponsor is Ericsson, with additional Bronze
sponsorship by Ciena.


We have a packed, high-quality agenda, with a number of talks on LTE and
White Space wireless networks, together with the latest high-speed fibre
technologies in the data centre, local loop, and rural locations.

We also have a follow-up from the UKNOF21 talk on the cure for
Bufferbloat, and a special presentation from Akamai's Network Architect,
Patrick Gilmore. Finally, we're planning some late-breaking material on
DDoS reflection attack prevention in the light of recent incidents.


At previous London meetings, we unfortunately had to turn people away
due to lack of space at the venues. We've been working to address this,
which is why we've switched to a much bigger venue, and it's great to
see we now have a record 135 attendees registered :-)

This success has however caused us to hit a different capacity limit two
weeks ahead of time, namely the number of attendees we can admit for no
fee from the sponsorship money we have raised. This is why we closed off
free early bird registration today, even though the venue can
accommodate more.

So, between now and the 18th, we're going to experiment with having late
registration (only) attendees pay their way via a registration fee.

This will be:
-  £50 (+admin, VAT) =  £63.65 between now and 12th April
- £100 (+admin, VAT) = £126.65 between 13th and 17th April,
   and for walk-ins on the day.

If you didn't register early, and still want to attend, please now
register at:

http://uknof25.eventbrite.co.uk/

I'd like to emphasise that we very much prefer UKNOF to stick to the
model of using sponsorship to keep attendance free for the majority of
attendees, this charging is an experiment for now, and we don't at this
point have any plans to do so for all attendees. We hope you understand,
but we are of course open to feedback as always.

If you or your organisation are interested in becoming an additional
UKNOF25 sponsor so we don't need to do this, slots are still available,
please do talk to us !


Getting back to the meeting:

Things will kick off Wednesday evening with the regular pre-meeting
Curry Social, sponsored by IXreach.

For those of you unable to attend in person, we will once again webcast
proceedings, with thanks to our webcast sponsors Bogons and Portfast.

At the end of the day there will be social drinks, sponsored by
hardware.com.

Look forward to seeing you all on the 18th !

OARC's 2013 Spring Workshop will be held on Sunday 12th, and the morning
of Monday 13th May 2013, in Dublin Ireland, at the same location as, and
immediately prior to the RIPE66 meeting.

Call for Presentations
---

We are soliciting presentations in all areas of DNS-OARC's
Operations, Analysis, and Research mission. Topics in the past have
included DNSSEC deployment and troubleshooting, analyses of new
threats, tools for improved operations, and research into stability
and performance of large and complex DNS installations.

This workshop continues OARC's tradition of having spring meetings
include a strong operational component. Presentations from DNS operators
are particularly welcome. We'll also gladly accept talks from DNS
researchers, as well as any other DNS-related subjects.

Please e-mail submissi...@dns-oarc.net with a brief abstract of your
proposed talk.

---

OARC Workshops are open to OARC members, presenters, and to all other
parties interested in DNS operations and research, subject to available
space.

Information on the venue and accommodation, with registration and other
details to follow, are available at:

https://www.dns-oarc.net/oarc/workshop-201305

Could it be an issue with DNS response size ? Responses with MX and/or

may or may not be related to use of EDNS and/or queries over TCP vs UDP.

However, it's not clear that such packets would be big enough to run up
against regular network-path MTU issues, which makes me wonder if you
might be the collateral victim of some half-arsed attempts to filter
back-scatter of DNS reflection attacks.
