UNSCHED RESOLVED OUTAGE DoeCEV 12 August 2005: 11:48 – 14:17PDT
Equipment: inr-000/packetshaper/ISP link
Date: 12 August 2005: Start: 11:48 End: 14:17PDT
Shortly before noon, a UPS in the DoeCEV failed. The failed UPS had supplied
power to (among other things) a media converter chassis which sat in the path
between inr-201 (a core router) and inr-000 (one of our border routers).
Routing within campus converged to utilize alternate paths as expected; however,
inr-000, which was isolated from the rest of campus, continued to announce
campus connectivity upstream.
These announcements attracted some return ISP traffic, and caused loss of
connectivity to some off campus sites.
Shortly after 2pm, power to the fiber media converter was restored, and all
traffic to/from campus along the commodity ISP path began flowing normally
