Re: FB?
The route-leak was something different that seems to have mainly hit west-Europe between 16:52 UTC to 17:08 UTC. There’s a few people in the *NOG communities still digging at the complete details of that right now, but it currently points to have originated from AS200020, impacting a few large upstreams for a short period of time. So unless this leak caused a catastrophic cascade in FB’s network somehow, it seems to be unrelated. It looked like a valid suspect because timing was very similar between the start of the FB outage and the leak.

Re: Virtual or Remote Peering
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.

Re: DWDM Mux/Demux using 40G Optics
Another alternative is to ask the http://www.beetlefiberoptics.com guys. They build muxes on spec and they can also provide a 1310nm wide-band port on their units which allows a 40/100G-LR4 aside from the 1550nm DWDM band. We’ve used some simple splitters (line/1310nm LR4/1550nm DWDM ports on a unit) and full passive DWDM muxes with a 40/100G-LR4 port on there and these work pretty good.

Re: GeoIP information
It'd really help if some larger content providers would give LIR's some tools to effectively manage GeoTargeting within IP allocations and the subnets therein that they own. In my experience it takes anywhere between 2 weeks and 6 month to get IP blocks effectively Geo-targeted. Google is one of the harder but most visible ones, their online form to change it doesn't do anything. Going through their NOC usually fixes an issue within 2-3 weeks. (Google engineers, idea to add tools for that at https://isp.google.com on a webmaster tool-ish management interface?) Akamai is usually pretty fast and changing maxmind will eventually follow up a lot of the remaining sites. But it's a slow process. Our strategy is generally to change the RIR DB entry to include the correct country and geoloc fields. Followed by a maxmind update request and then some direct strings pulled from friendly operator colleagues and a mail to the Google NOC.

Re: Cogent IPv6
Here in the Netherlands we got it 'free' (i.e. dual-stack on top of the IPv4 transit without extra cost) But we're currently looking into an alternative for a provider with non-broken IPv6 transit and cancel our contract with Cogent. They called us once asking how satisfied we were with their IPv6 transit. After bringing up the HE issue the conversation ended surprisingly fast. The Google depeering thing was the final straw, all our transits can provide a reasonably complete IPv6 prefix table, except for Cogent.

Re: IPv6
I second that, we're only getting ~2665 IPv6 prefixes from Cogent compared to the ~3650 from our other transits. (been like that for more then a year now) Cogent's stance on it is 'You're multihomed with other transits, so you're still reachable anyways' which strikes me as very odd for someone who's supposed to be selling global transit. They once called me asking about how satisfied we were with their IPv6 transit, but quickly ended the conversation once I asked about the incomplete feed and the HE peering refusal. Personally we don't see Cogent as a serious transit provider for IPv6 and have their v6 prefixes set with a very low priority. On 11/19/10 12:35 PM, Job W. J.

Re: Drop in IPv6 traffic
If I look at a tcpdump of our teredo relay which is announced to all our AMS-IX peers (and some partial and full transits), there's a lot of nntp and quite some torrent packets going over there, so it seems the majority of IPv6 traffic is due to content providers like XSnews providing 'freebies' to what otherwise would be a paid service. We've seen the same with our Eweka/Highwinds partial transit, once we announce 2001::/32 there, there's suddenly a big increase in traffic over our teredo from other exchange points prefixes we get from them, heading to free IPv6 news services some dutch providers hand out.

I ask because the AMS-IX is frequently used as an example that v6 is being heavily adopted. If it is all one source for one application, that is important information to the people fighting for v6 adoption. Going from peaks of 1.4 Gbps to 0.4 Gbps is impressive.
