At approximately 3 a.m. today, a main power component in the campus data center failed. The nature of the failure caused all redundant power systems, which normally would have activated, to immediately go offline for safety reasons. This consequently caused all computer systems in the data center and dependent services to go offline.
Services affected included VPN, Desire2Learn, Exchange, CUAccess, MyCUBoulder, MyCUInfo, www.colorado.edu and UCB Files. While Exchange email service is restored, it is experiencing delivery delays due to the recovery process.
Staff from Facilities Management and OIT, along with various vendors, restored power and worked diligently until all services were fully restored. Updates on the issue can be found at www.colorado.edu/oit/node/12611.
