At 3:00pm today the Jenkins Continuous Integration server (jenkins-ci.mcs.anl.gov) will be rebooted in order to patch a kernel vulnerability that is being exploited. The outage should last approximately 15 minutes. Only users of that system will be affected.

CIS would like to take the morning of Saturday, May 25th to upgrade the Zimbra server to the latest version 7 release. The outage would last from 9AM until 2PM, during which time you’d be unable to reach your mail or calendar. If this window poses a particular problem for you, please let us know …

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.

Hello everyone, There is currently an issue causing higher than usual network latency, and slow NFS filesystem access. Because of this access to MCS servers, and usability of MCS linux desktops may be affected. We will be sending a status update when we have more information. —- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science …
