Matlab License Renewed (until 2/2/09)

by

Due to a misunderstanding, IST thought that there was a 30 days grace period built into the license file, and so they thought the license file wouldn’t expire until 03/01/08. But as it turned out, that wasn’t true.

As a result, the matlab license server was down on 02/02/08 and 02/03/08.

The matlab license file has been renewed to 02/01/09.

We apologize for any inconvenience for the matlab downtime.

Network switch error detected

by

We have detected an error on the network switch that serves the EECS data center. While we are not currently detecting any impact on network performance, experience has shown that we will need to replace a 10Gig Ethernet blade in that switch. To minimize disruption, this board is now scheduled to be replaced between 07:00-07:30 tomorrow morning. If we detect any impact on service before then, the board will be replaced immediately without warning. We regret any inconveniences this may cause.

Mail delays due to last night’s power outage.

by

As a result of last night’s power outage, there were some mail delays (and some senders may have received 4-hour notices). Obviously mail has been queued up on the external (and some internal) systems, which caused a spike after the services have been restored. As of now there are still some delays, but things are getting better.

One of the spam appliances had an internal failure last night, which caused it to not be able to properly scan email and deliver it. As a result, there were about 54K messages queued up. It is currently going through the queue and delivering those messages.

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.

IRIS Website and Mailing Lists Offline Jan 15 Due to Server Maintenance

The IRIS website and all Sympa mailing lists will be offline briefly beginning at 10:30p.m. on Tuesday, January 15 due to server maintenance.

The IRIS webserver and Sympa database server will be patched and rebooted into a new kernel. Total downtime for both services should be less than 30 minutes.

Any mail sent to a Sympa mailing list during the outage will be accepted as normal, but wont be delivered until the database is back online.
