Servers Remain Up During Power Outage
Large swaths of Northern California, including the UC Berkeley Campus, are under a Public Safety Power Shutoff due to high winds and the associated wildfire risks. Our servers are located in the campus Data Center which is protected by a high capacity UPS. We expect that our servers will remain up for the duration of the outage. Thus far Internet connectivity also remains up although this depends on factors outside of the Data Center.
