PLEASE READ - IMPORTANT MESSAGE - PLEASE READ

SUMMARY: The Data Center in Rhodes Hall will be without uninterruptible power supply (UPS) from Saturday, April 24, 2021, at 11:00pm through Sunday, April 25, 2021, at 4:00am.

DESCRIPTION: During this outage, CIT will install new, redundant UPS devices for the Rhodes Hall Data Center.

WHAT DOES THIS MEAN FOR CAC CLUSTER/SERVER CUSTOMERS? The majority of CAC managed servers are protected with both UPS and Building (non-UPS) power. During the work window, servers will run on building power. We don’t believe we have any equipment running solely on UPS power. CAC staff will be available on Sunday to attend to any unexpected outages.

STATUS: Status will be posted.
