Interesting, I pick up Cogent in Toronto and saw some sort of issue
between them and sites I pick up out of AS577 (via in Cogent in
Chicago). BGP paths seemed to be there, but traffic dropped to almost
nothing for about 10min. By the time I got online to look, the issue had
resolved.  This was at about 02:05 Eastern to ~ 02:20.  Were they
perhaps doing some big upgrades ?
