Hi Folks,

On Monday October 20th 2014 we experienced a network in the Sutardja
Dai network zone.  Also impacted were the majority of off-campus
locations, because their connectivity terminates in this zone.  The
attached is the results of a review of this outage.

For those who don't want to read the whole document, the summary is:

"Spurious network traffic generated by a set of network switches being
configured in a lab environment resulted in the CPU capacity of
INR-304, one of the campus zone routers, being exceeded. This lead to
the router dropping its routing processes and ceasing to forward
packets. Once the source of the traffic was identified and removed
from the network, service was restored to the sites that were impacted
by the outage."
