Today's UPS planned maintenance has concluded successfully with no outage for Summit or Blanca.

Scheduled maintenance is currently in progress. We will provide updates as necessary.

Next week on our regular planned maintenance day the CU Boulder datacenter team will be conducting planned maintenance on the UPS that supports Summit and Blanca HPC in the HPCF. No outages are expected, and jobs will continue to be scheduled and run as normal.

While the UPS is under maintenance both Summit and Blanca HPC will be running on bypass power. Bypass power carries increased risk of disruption from instabilities in our utility power supply.
