Has it been known the exact time of the incident? I have found an article reporting that the cut occurred in the mid-day of Saturday 25th but nothing more precise. We would like to use such information for a BGP anomaly detection analysis that we are carrying out in our research centre.
Thanks in advance,

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.
