The Uninterruptible Power Supply (UPS) #4 located in the General Services Building (GSB) data centre experienced a hardware failure which resulted in several non redundant power supplied servers to become unavailable and as a result several services were either unavailable or were slow to access.
Campus Computing ID (CCID), Judas, LDAP (Lightweight Directory Access Protocol), MX mail and Samba users were potentially affected by this outage.
The affected users were not able to access or experienced delays with the following services CCID, Judas, LDAP, Mail, Pubcookie and Samba.
UPS #4 experienced two separate hardware failures. The UPS and it’s transformer both failed at the same time resulting in total loss of power to connected devices.
The affected servers were moved to alternate power supplies (utility power or alternate UPS’s) to restore service.
Vendor support technicians will perform repair work to bring UPS #4 and it’s transformer back to full health in the next few weeks.
None as UPS# 4 and it’s transformer will be be overhauled and repaired.
