Reminder: Maintenance to affect sites dependent on AFS

The Andrew File System (AFS)—a central file storage, sharing, and retrieval system that U-M websites rely on—will be relocated to a new data center on February 24.

Work will be done during the normal maintenance window on Saturday, February 24, 2018, starting at 11 p.m. At that time there will be a brief outage expected to last no longer than one hour. This time frame is ideal when U-M website traffic is usually at its lowest.

The relocation will allow AFS to operate in a more modern data center that uses up-to-date hardware, making the system more resilient and impervious to failure. In the event of a problem, ITS will roll back AFS to the existing servers, which will not be touched during the maintenance (other than to copy data).

No action is needed on campus. You should expect a brief outage during the maintenance window. After the all-clear is given, if you observe website problems that you believe might be related, please contact the ITS Service Center.
