Mailing List maintenance, Friday, Jan 23, 6pm

by

The Department’s mailing list server, lists.eecs.berkeley.edu, will be shutdown, upgraded and restarted starting at 6pm tonight. Mail sent to department mailing lists will be delayed during the outage, which is not expected to last longer than 15 minutes. The lists.eecs web interface will also be unavailable during this time.

A minor upgrade to the mailing list software was recently released which fixes a bug that was introduced in the previous version. Some of our mailing lists were affected by this bug, so we are upgrading with short notice.

The upgrade has been applied to a test server with no issues, and we expect the total downtime to be less than 5 minutes.

[Actual downtime was 7:17pm – 7:18pm.]

Mailing Lists Maintenance, Sunday, Jan 4th, 10pm

The Department’s mailing list server, lists.eecs.berkeley.edu, will be offline beginning at 10pm for maintenance. The mailing list software will be upgraded to Sympa 5.4.4. This is a minor upgrade which consists of numerous bug fixes.

Service should resume no later than 11pm, probably much sooner.

During the outage, any mail sent to a department mailing list will be held for delivery. All mail will be delivered when the maintenance is completed.

Multiple Services Offline for About Eight Hours

by

The EECS website, FTP server, Jabber server and Sympa mailing-list server were offline for about eight hours on Sunday, Dec 28, 2008 beginning at 2:48 p.m.

The virtualization cluster that hosts these services experienced a failure when the network switch that supplies its management network was rebooted during the [scheduled network maintenance](https://iris.eecs.berkeley.edu/news/2246-eecs-network-maintenance-sunday-dec). We didn’t notice the failure until this evening, but were able to restore service quickly once we realized what was wrong.

I apologize for the length of the downtime and am planning on working to make the cluster more robust and improve our notification and monitoring so that any future issues will be noticed more quickly.

Mailing list messages delayed

by

The EECS mailing list server, lists.eecs.berkeley.edu, ran out of memory and stopped processing messages around 4am on Friday, November 7. It was restarted around 9am.

During the outage, the server was accepting incoming messages but not redistributing them. Once it was restarted all messages were then delivered. No messages should have been lost.

We will be adding more memory to the server in the next day or two, which should prevent this problem from occurring again.

We apologize for the inconvenience.

Brief Interruption of Some IRIS Services

by

The department website, Jabber and Sympa services were briefly interrupted this morning due to an issue with the cluster that provides them.

Each service was unavailable for a few minutes between 10:00 a.m. and 10:30 a.m. as the server cluster they run on was restarted. Restarting the cluster was necessary to alleviate a deadlock in the clustered file system used by the services.

My apologies for any inconvenience this has caused, I’m looking into how to avoid this situation in the future and bring more stability to the cluster.

Unexpected Outage of Dept. Website, FTP, and Mailing Lists

by

Due to some necessary maintenance to some SAN hardware, the department’s website, FTP server, and mailing lists experienced brief outages this evening beginning around 6:24 p.m.

The website and FTP server were only offline for about six minutes, but mail sent to lists handled by lists.eecs.berkeley.edu (Sympa) during the outage may have been delayed up to 45 minutes. I apologize for any inconveniences this may have caused.

The server hosting the department web and FTP services along with the one hosting the database used by Sympa went offline when they unintentionally lost their connection to the SAN during maintenance. The maintenance was last-minute and shouldn’t have caused any disruption, but it didn’t quite go as planned.

Hardware has arrived to allow us to make redundant connections to the SAN for these services which will make them more resilient in future situations like this one. We plan to have the hardware installed and in use soon.

EECS Website, FTP, Jabber, and Sympa Offline for Urgent SAN Maintenance

by

Due to some urgent maintenance to the SAN, the EECS Website, EECS FTP server, Jabber, and Sympa (mailing lists) services will be offline from 5:00 p.m. to 6:00 p.m. on Tuesday, September 23, 2008.

The servers hosting the aforementioned services lack redundant connections to the SAN which prevents them from remaining in service during the maintenance. We realize this is an unfortunate limitation and are procuring new hardware which will add the redundancy necessary to handle similar situations more gracefully in the future.

Our apologies for the short-notice and inconvenience.
