Renesys published a brief writeup of the incident yesterday.   We called it
at 09:13 UTC on the 25th.   Lots of interesting outage and transit-shift
effects to see in the East African BGP data that day.  We also report some
shifts in latency based on active measurement, as everyone's traffic jumps
onto the surviving connectivity through SEACOM.   Kenya Data Networks
(AS33770) did a particularly good job staying alive by virtue of their
upstream provider diversity, kudos to them.
