Unplanned network outage in part of the 3rd floor of Cory Hall due to switch failure. Wired and wireless access is affected. We are working to restore access to wireless by moving to a different switch.

We have contacted the vendor for a replacement and will re-route wired connectivity if the outage on this device will be for an extended period of time.

BWRC Network around 1:00PM on Feb 9

by

IST staff will replace the media converter at BWRC to try to solve the outgoing packet loss issue. It should take about 10-15 mins. BWRC outgoing network traffic will be affected. BWRC internal network traffic will still remain working. We will schedule about 1 hour maintenance window in case something unexpected occur. If you have any question, please send email to networks@eecs.

EMERGENCY SCHED MAINTENANCE: potentially campus-wide impact

EMERGENCY SCHED MAINTENANCE potentially campus-wide impact thu 2 feb 2012 1500 – 1600

Equipment: inr-002 campus border router Location: potentially campus-wide impact Date: thu 2 feb 2012 Start: 1500 End: 1600

Description: an FPC (interface module) in inr-002, one of UCB’s two border routers connecting to the CalREN networks, has failed and must be replaced. i’m scheduling an emergency maintenance window 1500-1600 tomorrow, thu 2 feb 2012, for swapping out the failed FPC with a replacement unit. (this assumes the replacement FPC will arrive early enough tomorrow for the scheduled maintenance window.)

FPCs are hot-swappable (and the one currently in the router is already offline), so i don’t anticipate any disruption to campus’s external connectivity. however, to be doubly sure, i will have previously moved all external traffic off this router and onto inr-001, the redundant border router.
