Planned network outage, March 25, 7-8am

March 25, 2008 by Janet Shu

There will be network maintenance at Soda 2nd floor on Tuesday March 25th between 7:00AM and 8:00AM. During this network downtime, both cronus and rhea will be off the network, so departmental NIS and time services will be down. Coeus and Project will be down, so all home directories and project file storage space will be unavailable.

We expect the actual down time to only be several minutes but we are scheduling a larger window for the outage in case we encounter any unexpected problems.

Please make your plans accordingly.

EECS Network Outage

January 27, 2008 by IRIS Staff

From some time late last night until about 11:30 this morning, much of the EECS network was down due to a major power failure in the Soda Hall Network Center.

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.
