Planned Maintenance and Power Downs at Butrovich Data Center - AVO Website Service Outage

On Saturday, May 13, and Saturday, May 20, UAF Facilities Services and Office of Information Technology will be conducting a planned maintenance at the Butrovich Data Center (BDC) to integrate a new Uninterruptible Power Supply and perform essential electrical updates. The BDC is a critical facility that houses computing and networking hardware for the University of Alaska system, including the servers of the Alaska Volcano Observatory (AVO). This maintenance work is necessary to ensure the continued high-availability capabilities of the data center.

During the maintenance, all electrical systems in the BDC must be powered down completely. Consequently, all services and systems within the BDC, including the website, will be temporarily unavailable. AVO's monitoring capabilities will be mostly unaffected and we will continue to issue formal scheduled and event-driven notifications as needed during the outages.

Please take note of the following maintenance schedule:

Saturday, May 13: The power down will commence at 4:00 AM and last until 8:00 PM.
Saturday, May 20: The power down will commence at 3:00 AM and last until 10:00 PM.

During these maintenance periods, the primary responsibility for reporting on volcanic activity in Alaska will be handled by the USGS Volcano Hazards Program. You can access their updates at

If you have any questions or concerns regarding this maintenance, please feel free to contact Scott Crass at

We apologize for any inconvenience caused by these necessary maintenance activities and appreciate your understanding as we work diligently to ensure the continued reliability and performance of the Butrovich Data Center.
