    Scheduled maintenance on power infrastructure at the Downtown Data Center will require all General Environment clusters (granite, notchpeak, kingspeak, and lonepeak) and standalone biochemistry and cryo-EM servers to be taken offline from the evening of January 21 to the morning of January 22.

    Critical services, storage systems, virtual machines (VMs), and the redwood cluster in the Protected Environment are on generated power and should not be affected by this outage.
