Third Unplanned Power Outage to 165 Cory

by

Report from Scott McNally:

“Power was just lost again at 3:40pm Wednesday, 4/10/13. We will have to triage the number of machines we allow on in this room once we restore power. Then we still have a power shutdown on Friday to replace the faulty breaker.”

Mailed earlier today to the Cory Sysadmins maillist:

“Campus is planning a shutdown of Electrical Services to Computer Machine Room 165 and the East Side 1st floor of Cory Hall on Friday, 4/12/2013, between the hours of 9am-Noon to replace the faulty breaker. We are currently operating critical equipment only in room 165. In fact we insist no additional equipment be turned back on at this time until after the repairs on Friday can be made. If you are able to shut down equipment that may not be needed between now and Friday, we ask that you do so.”

On Tuesday evening these servers will have operating system patches installed which require a restart. They will be restarted automatically at 7am Wednesday morning and should be back in service by 7:15am.

These servers will now be patched (and rebooted if necessary) on the morning following first Tuesday of each month, the same schedule as our Windows servers.

EECS-Secure wifi outage due to power failure in Soda Hall

by

A brief power outage in Soda Hall led to an outage in the EECS-Secure wifi, though other EECS wifi SSIDs remained operable.

The cause of the outage was due to the radius servers failing to automatically power on again once power was restored, so they had to be started manually. We will review the configuration of these servers in an effort make them more resilient to such outages.
