This weekend is a CIS IT Maintenance weekend. Please see the details below. The network outage window is 4 hours, though actual interruptions will be brief and sporadic as routers and switches are rebooted. The systems are redundant, so interruptions should be brief, but an outage window is announced in case unforeseen problems occur. Please …

The router is back up, and has been for a while, but we’re still tracking the issue that caused the reboot in the first place. So things should be working, but network performance is degraded at the moment until we isolate the problem host.

The MCS router’s configuration was lost in the reboot. We are in the process of reloading it from a current backup. Things should be back within the hour, unless something goes very wrong.

The MCS network router was unresponsive and is in the process of being rebooted. Most wired MCS-hosted machines are unavailable, except for those hosted in building 221 (web server, mail server, etc.). Login and compute nodes are unreachable at the moment. Will send updates as we have them.
