Wireless Network Slowdowns
Resolved as of 2008-10-06 13:42:00
AirBears In EECS
AirBears wireless to some locations in EECS (particularly BWRC) was disrupted whereby AirBears clients could not get a lease. Other EECS WLANs were not affected. One wireless controller was shut down and all APs are back up on the other controllers. This may have resulted in a brief outage for some wireless clients.
We will do some more testing on the suspect controller tomorrow morning.

Cory Transformer Upgrade
Physical Plant will be shutting off all the power to Cory Hall to switch
transformers on Wednesday night, June 4th from 7pm to 9pm. This will
allow upgrade of our back up transformer located in the basement. The
building will be closed from 6pm until 9pm for this event. Please ensure
your lab equipment and computers are prepared for this event.
Please contact Scott McNally for questions or Mark Davis (642-1468) in
room 253, Cory Hall.
Note that CUSG will be on-site during this time, and will coordinate the shutdown of CUSG-supported servers in Cory Hall, and later will get them back online when the power is restored.
CUSG will attempt to power-off all CUSG-supported Cory Hall workstations (Windows PCs and Linux workstations) starting at 5:30pm. CUSG will power-off all CUSG-supported Cory Hall servers beginning at 5:45pm. Some may be online as late as 6:30pm, as we continue shut-downs remotely. Servers will be brought back online as soon as power is restored.
Soda Hall computer services should continue normally.

EECS Network Outage
Two circuit breakers feeding both the power distribution system and the A/C tripped causing the outage. IDSG staff responded to the outage as did a UCB electrician who were able to restore power The electrician is investigating the cause but we don’t yet know what the cause was.
Thanks to many EECS staff who helped during this outage to get things going again.
