Re: Cogent input
At $JOB-1 we used Cogent. Lots of horror stories had been heard about them. We didn't have such problems. Had nx1Gig from them. On the few occasions where we had some slight issues, I was happy to be able to get through to some one useful on the phone quickly, and not play pass the parcel with call centre operatives. and at least in the quantities we were buying they were significantly better value than others, which was the primary reason we went with them. andrew On Thu, Jun 11, 2009 at 2:55 PM, Paul Stewartpstew...@nexicomgroup.net wrote: Our experience with them was at least one major (longer than an hour) outages PER MONTH and many of those times they were black holing our routes in their network which was the most damaging aspect.

Re: Cogent input
Hi Justin, I'm in search of some information about Cogent, it's past, present and future. I've heard bits and pieces about Cogent's past over the years but by no means have I actively been keeping up. We recently got a 10-gig port in Oslo from them. Price-wise they were competitive but absolutely not in a leauge of their own - a couple of other large providers matched their offers. In the end the main differencing factor for us was that their PoP happened to be in the same building as our data centre, so no local access was required (unlike the others). The link hasn't been up for very long so I can't comment on long-term reliability issues, but so far I've been _very_ happy with them, everything was up and running just a couple of days after we ordered, and the staff we've had contact with have been knowledgeable and helpful. The service has performed as expected: latency has been low and I haven't noticed any sub-optimal routing (trampolines) or packet loss. We multihome, so we're not too concerned about potential de-peerings. I would not single-home to any of the transit-free networks anyway, as any of them could end up on the receiving end of a de-peering.

Re: Cogent input
Hello, * Stephen Kratzer We've only recently started using Cogent transit, but it's been stable since its introduction 6 months ago. Turn-up was a bit rocky since we never received engineering details, and engineering was atypical in that two eBGP sessions were established, one just to advertise loopbacks, and another for the actual feed. The biggest issue we have with them is that they don't allow deaggregation. If you've been allocated a prefix of length yy, they'll accept only x.x.x.x/yy, not x.x.x.x/yy le 24. Yes, sometimes deaggregation is necessary or desirable even if only temporarily. Interesting. I requested exactly that when filling in their BGP questionnaire, and they set it up - no questions asked. Also, we have a perfectly normal single BGP session. The loopback address of the router we're connected to is found within the 38.0.0.0/8 prefix, which they announce to us over that session like any other route. And, they have no plans to support IPv6. I have been promised, in writing, that they will provide us with native IPv6 transit before the end of the year. I'm based in Europe, though. Perhaps they're more flexible and customer-friendly here than in the US? Best regards, -- Tore Anderson Redpill Linpro AS - http://www.redpill-linpro.com/ Tel: +47 21 54 41 27

Re: Cogent input
Hi! Cogent's official stance on IPv6 is that we will deploy IPv6 when it becomes a commercial necessity. We have tested IPv6 and we have our plan for rolling it out, but there are no commercial drivers to spend money to upgrade a network to IPv6 for no real return on investment. Thats strange they are running pilots with customers on v6 in Amsterdam. Not really so strange. ISPs often pilot features (v6, multicast, etc) that they have no immediate intention of deploying, so that they have experience if and when it becomes profitable/sensible to deploy them. Not from what i have been told, but hey i am not working there. We got a v6 transit offer as pilot from them so perhaps they are moving towards live service Would not be strange in this current stage... Bye, Raymond.

RE: Cogent input
I'm aware of some (regular?) depeering issues. The NANOG archives have AFAIR, there has never been a black-holing, just disappearance of routes. If you are properly multihomed, this is irrelevant and you continue to eat your ice cream and chuckle while they fight it out. It's amusing, really. I also know that their bandwidth is extremely cheap. This of course creates an issue for technical folks when trying to justify other upstream options that cost significantly more but also don't have a damaging history of getting depeered. It's not as relatively cheap as it used to be. A variety of others can be had in the same ballpark (Telia, Tiscali, Seabone, etc.)
Re: Any2 Exchange experiences to share?

We are in San Diego and have easy access to the exchange via transport offered by our data center facility who does have physical presence at OWB, but *we* are not physically in OWB, ~4.5ms away and some $ for transport to OWB. All things considered, the cost will be about the same to route via Tier 1 transit providers from San Diego as it will be to transport to OWB to the exchange. The basic question is, Does it improve my network enough to connect to the exchange? If it's cost neutral, I'd go with peering. Additional vectors / choices are always useful. Plus as your network grows, you will get a cost benefit from the peering as that is fixed- cost. (Actually a step function as you upgrade, but you get the point.) Any2 runs a fine IX. Very few problems. OWB has had some issues with power in the past, but I think (hope) they are all resolved. -- TTFN, patrick

Our PI space is currently broken up to 1) let us effect some measure of load-balancing with Cox (any prefixes we advertised out Cox instead of our much larger tier-1 resulted in a wildly disproportionate amount of preference given to Cox; not sure why) and 2) let this new venture get started with a reasonably-sized allotment of IP. It will be advertised out local providers in that area and also at our main peering point with significant prepending. Visa versa for our other prefixes. We have to deaggregate a little bit to make this work (but not excessively of course). I have been promised, in writing, that they will provide us with native IPv6 transit before the end of the year. I hope at least some SPs make this commitment back in the states. I can't find any tier-1s that can provide us with native v6.

Don't know if they count as Tier 1 on your list, though. VZB has given me tunnels for a while, hopefully they'll get their pMTU issue fixed so we can do more interesting things with it. -Paul
RE: Cogent input
NTT (2914) and GBLX (3549) both do native v6... most everyone else on the tier1 list does tunnels. :( There are some nice tier2 networks who do native v6, tiscali and he.net come to mind. -John -Original Message- From: Paul Timmins [mailto:p...@telcodata.us] Sent: Thursday, June 11, 2009 4:00 PM To: Justin Shore Cc: NANOG Subject: Re: Cogent input I hope at least some SPs make this commitment back in the states.

Re: Cogent input
Good morning, * John van Oppen NTT (2914) and GBLX (3549) both do native v6... most everyone else on the tier1 list does tunnels. :( There are some nice tier2 networks who do native v6, tiscali and he.net come to mind. It's worth noting that being a v4 tier1/transit-free network doesn't necessarily mean that they're the same in the v6 world. For instance, Google appears to be a transit-free v6 network. It wouldn't surprise me if the same is true for other big v6 players like Tinet and HE. Anyway, when looking for v6 transit the following page might be useful: http://www.sixxs.net/faq/connectivity/?faq=ipv6transit Best regards, -- Tore Anderson Redpill Linpro AS - http://www.redpill-linpro.com/ Tel: +47 21 54 41 27
