Hurricane Sandy’s affect on the core BGP table

A couple of interesting graphs. You can see in the following diagrams how Sandy affected the BGP table. These images I got from the CIDR report

450 AS numbers disappeared as well as roughly 3000 prefixes. Which of course gradually returned

I don’t have figures for RTT to various sites as my guess is that a fair amount of trans-Atlantic traffic would’ve been quite higher.

Update: RIPE has a good RTT graph over here
