Ticket Description: Power outage in Lausanne

Problem Description:

Yesterday, February 22, between 20:15 and 21:35 there was a large power outage in
the Lausanne area that affected part of our equipment. Most equipment survived the
outage thanks to UPS systems, except for swiESP2, which lost power completely
between 20:15 and 20:21. Thus EHL lost redundancy during that time. Traffic flow
was not affected as the primary access still had power.
The backup BGP session to IMD went down around 20:44 and came back up at 21:35.
As the primary session was up the whole time, traffic flow was not affected either.
It's suspected this was also related to the power outage.


From 2010-02-22 20:44 until 2010-02-22 21:35
Impact: no more redundancy
