I noticed just a little while ago that we're having a lot of DNS fail. Initial findings were that several of the root-servers we were trying to reach via our TWTelecom link were unreachable after 2 hops into TWT.
4 64-128-130-233.static.twtelecom.NET (64.128.130.233) 2.399 ms 2.298 ms 2.338 ms 5 mia2-pr1-xe-1-3-0-0.us.twtelecom.net (66.192.253.18) 11.571 ms 11.552 ms 9.467 ms 6 * * * 7 * * * 8 * * *
For instance, a.root-servers.net is pingable from a rackspace server, but not from our network (unless I shut off TWT, at which point it is, but it's apparently not the same a.root-servers.net instance rackspace sees). I assume this is one of the root-servers being anycast.
Shutting off our BGP with TWT didn't appear to help (though the root-servers became reachable)...so I assume there's more going on
just TWT routing fail.

No, not at all. It's just totally pointless. Any IPv6 address is just as pretty as a synthesized name. Maybe even prettier. Do you prefer "2001:db8:1::2" or "20010db8000100000000000000000002.rev.example.com"?

A threshold you should use to view the general instability (which I find valuable, you may as well) is route views data.
If you look at the BGP UPDATES archive sizes, you can see when something happens, e.g.:
http://archive.routeviews.org/bgpdata/2011.11/UPDATES/
Take a look at the size of the updates.20111107.1400.bz2 file and the 1415 file. They are abnormally large compared to a normal period of time. This shows there were a lot of updates out there being processed and a reference to levels of instability.

Actually, it looks to me like they mean "Time Warner", because that's what they said.
The company once known as "Time Warner Telecom" has always been a different entity, and hasn't been known as that in some time, now being called "twtelecom." Much of that company is what was once known as inc.net, a Milwaukee area provider of the '90's.
Time Warner Cable appears to have experienced an implosion this morning, being out of service for about 11 minutes. During that time, packets originating here in Milwaukee quickly died in Chicago;

Using the looking glass from TWtelecom, we saw 30-60min outage (roughly 8:30AM to 9:30AM CST) between the Kansas City location and our own server room in Kansas City. Other TWtelecom locations appeared to be unaffected. Perhaps TWtelecom is served by Timewarner or shares equipment in KC. Either way, none of our KC customers who were served via TWtelecom or Timewarner were able to reach us. Packets would hit Level 3 Communications and die in either direction at the border between L3 and TW. FWIW, TW was showing a good BGP route to us and vise versa. http://lglass.twtelecom.net/

My 10.4r1.9 boxes died also but I saw interfaces go down whilst bgpd seemed stable.

We seem to be having some problems with our tata links - first seen in EU about 45 minutes ago, now we're seeing problems in NA. I'm focused on DNS, so I'm seeing a lot of timeouts/servfails, but our networking folks are talking about links dropping.
Anyone else seeing oddness on the NA Internet right now?
http://downrightnow.com/ confirms - something is up.
There are widespread issues across the Internet; certain versions of Juniper firmware have core dumped after seeing a particular BGP 'UPDATE' message.
(That's the running theory at least).
It's affected multiple service providers, globally, not just those connected to TATA.

On our side all our 10.3R2.11 core dumped which made all our interfaces flapped. I've been told 10.4R1.9 is affected too.

Gizmodo is reporting problems at Time Warner Telecom .... we're suffering from it too and calls to the NOC have not been answered so far...
does
anyone have any further information?

Actually, it looks to me like they mean "Time Warner", because that's what they said.
The company once known as "Time Warner Telecom" has always been a different entity, and hasn't been known as that in some time, now being called "twtelecom." Much of that company is what was once known as inc.net, a Milwaukee area provider of the '90's.
Time Warner Cable appears to have experienced an implosion this morning, being out of service for about 11 minutes. During that time, packets originating here in Milwaukee quickly died in Chicago;
1 76.46.192.1 8.320 ms 9.900 ms 7.974 ms 2 24.160.230.32 7.967 ms 5.975 ms 8.479 ms 3 24.160.229.132 8.471 ms 7.969 ms 10.991 ms 4 24.160.229.193 9.972 ms 9.973 ms 24.160.229.197 9.985 ms 5 * * * 6 * * *
while packets destined for RR all seemed to be headed out to SJC, from what I can tell.

On #IX there are rumours about Junos version 10.3R2.11 being core
dumped and
rebooted, which makes sense.
Perhaps related to Juniper PSN-2011-08-327? Did the whole router reboot, or just the service module?
We saw one TATA session, and one Abovenet session flap.

Using the looking glass from TWtelecom, we saw 30-60min outage (roughly 8:30AM to 9:30AM CST) between the Kansas City location and our own server room in Kansas City. Other TWtelecom locations appeared to be unaffected. Perhaps TWtelecom is served by Timewarner or shares equipment in KC. Either way, none of our KC customers who were served via TWtelecom or Timewarner were able to reach us. Packets would hit Level 3 Communications and die in either direction at the border between L3 and TW. FWIW, TW was showing a good BGP route to us and vise versa. http://lglass.twtelecom.net/

FWIW, We saw issues here in Indianapolis between TWTC and L3 up until a few minutes ago.
