File System Issues

During our downtime this morning we replaced our aging file server. Despite our efforts, the linux cycle servers are not reliably maintaining their connection. We are re-booting the file server to (hopefully) bring things to a good state. This reboot will impact all our systems for 10 minutes or so. We apologize for the inconvenience.

Downtime: Tuesday, January 30, 2007

On Tuesday, January 30, 2007, we will have a scheduled downtime from 4:00am to 8:00am EST. Please note that this coincides with an OIT-scheduled interruption of all campus networking services from 5:00am to 7:00am EST. For details on the OIT maintenance, see their posting.

Scheduled work includes:

  • Updates to our network switches
  • Updates to our e-mail infrastructure

UPDATE: As of 8:00am, the software upgrade to our spam filtering software was not complete. We are going to bring up the mail infrastructure anyway and then turn on spam filtering later this morning when the upgrade is complete. You are likely to see more spam this morning during this time.

UPDATE: As of 8:45am, spam filtering is now back online. We only were able to partially upgrade the software and we will be scheduling another downtime soon.
