On Thursday, April 10 between 6:30 and 8:30 a.m., a maintenance window has been scheduled for various CAEN servers. This maintenance window is primarily intended for the application of security patches that Microsoft is expected to release during the same week. The patches correct serious operating system and application software vulnerabilities that could lead to computers being compromised. Other maintenance, including maintenance on Linux systems may also be performed during the window. These efforts may interrupt some services that CAEN provides. The interruptions will typically last less than 15 minutes, but could last longer. The following services may be affected:

  • Linux login servers (accessed as login.engin.umich.edu, vnc-oncampus.engin.umich.edu, or vnc-twofactor.engin.umich.edu and also known as VNC servers).
  • Some applications on CAEN-supported Windows lab and research computers.

In the event that maintenance is not required on this day, this outage will be canceled with as much advance notice as is possible.
