For background on the Greenland Connect cable, the UKNOF presentation I
presented (built by Heller, Harland, and I) in 2009 is here at
http://bit.ly/GrConnect - You can get past Iceland for sure. Just not for
free.

(Honorable mentions in all of this for AMS-IX, LINX, Nick Hilliard, Andy
Davidson and Will Hargrave. Remco van Mook got the Golden Jökulhlaup for
his part).

The route was cost prohibitive as you guessed. There was reach-ability from
the EU to CA via RVK and GOH, The built paths were CPH-RVK-GOH-YHZ and
LON-RVK-GOH-YHZ. While the GOH route were most prohibitive, the RVK paths
less so. It was much cheaper to route LON to LGA via Hibernia. I like it as
a back up path. So did a few banks. But cost. Do I think this is a viable
path? Yes. Will it ever come down in cost? I'd go back to try this again.
Maybe things have changed?

Network & Socialize @ SAFNOG-3

[Mark Tinka]

Hello all.

The Internet is built on mutually fulfilling human connections, and at
this year's SAFNOG meeting, we look forward to further enhancing these
opportunities.

There are a number of networking and social engagements planned for you,
our delegates, at SAFNOG-3 in Durban:

a) SAFNOG-3 will be co-located with iWeek, at the very same
   venue. You will have the chance to interact with several
   Internet personalities attending iWeek to understand their
   perspective.

b) Prior to the start of each day, as well as during the lunch
   and coffee breaks, you will be able to surround yourself with
   fellow delegates and exchange ideas about the topics that
   will have been presented, or your own personal and
   professional experiences working on the Internet.

c) NAPAfrica, Africa's largest Internet exchange point, will
   hold a Beers for Peers event at the California Dreaming venue
   in Durban. You are all invited to attend, free of charge,
   upon presentation of a ticket which will be handed to you at
   the registration counter.

d) SEACOM, Eastern Africa's first submarine cable system, will
   hold the Closing Social Dinner at the Joint Jazz Cafe in
   Durban. You are all invited to attend, free of charge, upon
   presentation of a ticket which will be handed to you at the
   registration counter.

e) For a bit of fun, an iPhone 7 Plus Jet Black, 256GB and iPad
   Pro 12.9-inch Space Gray, 512GB, Wi-Fi + Cellular, will be up
   for grabs in a lucky draw at the NAPAfrica and SEACOM events,
   respectively. So please carry your business cards and stand a
   chance to win one of these cool devices.

For more details on the agenda and timing listings, please see:

"Bell spokesman Nathan Gibson says the first cut was by a highway
construction crew near Drummondville, Que.

He says service wasn't impacted in any significant way because of
redundancy in the network until a second major cut near Richibucto, N.B.,
by a logging company in a densely forested location.

He says the second cut was difficult to access and took some time to locate
precisely, and the site's inaccessibility slowed the arrival of heavy
equipment and repair crews."

Re: Virtual or Remote Peering

[Jeroen Wunnink]

It’s simply extending an exchange vlan over an l2circuit. It works as good as 
the provider’s network and the intended use for it.
As a customer you either want to reach an exchange on a location you’re not at 
or get a smaller circuit then an exchange would normally sell you directly.

Although you pay the provider that provides you the circuit into the exchange 
as a reseller, you are a full member there.

There’s some controversy in the community on its intended use. 
Some companies simply use it to get onto an exchange within a metro or country 
without actually getting kit into an exchange’s POP to save money.
Others use it across country borders/oceans and use a high-latency circuit to 
get onto a local exchange, which defeats some purpose of a local internet 
exchange. (short low latency-paths into local networks)

Then again, getting a circuit from the US into an big exchange like LINX, AMSIX 
or DECIX can be very appealing on both saving cost of transit and keeping your 
as-paths (artificially?) short.

How well does this service work? I understand it usually involves

like a service for ISP that would like to peer, but have relatively small 
volumes for peering purposes or lopsided volumes.
