real data [Re: General Internet Instability]

Mon Nov 7 17:01:13 UTC 2011

Here's some real data for those interested.  It seems a quick view seems many TATA <-> Level3 and TATA <-> GBLX sets of instability.

Combined with the overall update levels seen over that 30 minutes, we saw ~1.566M updates at route views.

Compared with the 24h prior (2011.11.06 14:15 as reference) we see ~17-20x the updates in the same time period.  Now take your control plane and make it work 17-20x as hard, and you can see why we had some even general instability.

I don't have better tools for doing a more detailed analysis at this time, but this should get you started in talking to others about what happened.  (There were no stand-out prefixes for this time-period, they all had about the same number of updates per prefix).
