ACG Web/Database Applications

The Department website (www.eecs/www.cs), mailing list server (lists.eecs) and ACG application server (buffy.eecs) will be offline from around 8am-8:15am Thursday morning.

The Storage Area Network (SAN) that serves these machines will be reconfigured at 8am which will result in a brief outage. Ideally all services will remain available but service might be disrupted for ten to fifteen minutes.

The Storage Area Network (SAN) that hosts the virtual machine images for www.eecs, buffy.eecs and lists.eecs briefly stopped serving the storage around 1:45am. The virtual machines stopped at that time and were restarting this morning around 9:45am.

The SAN software that is causing this problem is due to be retired in the next few weeks.

Starting around 10:30PM tonight, the EECS website, Mailing List and IM services (aka www.eecs, lists.eecs and Jabber) went down due to a problem with EECS Storage.

While EECS Storage is back up and most affected services — including access to home directories, project storage, Software Warehouse, and IMAP — recovered, Maillists and IM stayed down due to a backend database server that had not yet recovered from the storage outage. The Xen cluster that provides these services lost all contact with the SAN and and to be restarted.

Staff are working now to bring these remaining services back up.

In the meanwhile, if you are still having problems accessing your home directory, project storage, Software Warehouse, or IMAP, please contact the EECS Helpdesk.
