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 avo.alaska.edu 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 https://www.usgs.gov/programs/VHP/volcano-updates#avo">https://www.usgs.gov/programs/VHP/volcano-updates#avo.

If you have any questions or concerns regarding this maintenance, please feel free to contact Scott Crass at scott.crass@alaska.gov.

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.

VOLCANO ALERT LEVELS

NORMAL
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.

ADVISORY
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.

WATCH
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway but poses limited hazards.

WARNING
Hazardous eruption is imminent, underway, or suspected.

AVIATION COLOR CODES

GREEN
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.

YELLOW
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.

ORANGE
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].

RED
Eruption is imminent with significant emission of volcanic ash into the atmosphere likely OR eruption is underway or suspected with significant emission of volcanic ash into the atmosphere [ash-plume height specified, if possible].
