EECS Network Outage

by

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.

Network Disruption

by

From about the time of the routing changes this morning in Soda, some systems have had trouble with NFS mounting of partitions from coeus and project. The problem appears to be isolated to specific systems. The problem does not affect all systems moved to a new router this morning. The problem does not appear to be reproducible on all systems on any specific network.

At least one affected client machine seems to be fixed after a reboot.

Staff are continuing to investigate this issue.

Network Outages in Soda Hall

by

There will be some brief network outages in **Soda Hall** on Thursday morning between 07:00–07:45. We will be changing the routing for the following subnets:

* 2nd floor
* 128.32.42.0/24
* 3rd floor
* 128.32.34.0/24
* 128.32.112.0/24
* 4th floor
* 128.32.37.0/24
* 128.32.132.0/24


I expect the outages to occur one at a time and each should be less than just a few minutes each as we transition the routes from the old router to the new infrastructure. I regret any inconvenience this may cause.
