UNM's network experienced a major outage at 8:09 a.m. on Friday, Feb. 25. The core network was down approximately 41 minutes, with all network services on Main, North, South and Branch campuses, and UNM Hospitals, being affected. The core network server was restored at 8:50 a.m., and most network services were also restored. Some phone and voice mail services are still being restored and are expected to be fully functional later today.

The cause of the network outage was two-fold. A generator supporting the core network equipment was undergoing its monthly scheduled maintenance test, and the uninterruptible power supply (UPS) providing backup power failed, bringing down the core network. The redundant core network equipment, located in another building and intended to provide redundant backup connectivity to ensure high availability, also went down due to internal hardware issues. Essentially, two "safety nets" failed, both due to internal hardware issues. These two events in conjunction caused the entire UNM network to fail.

IT is investigating this dual failure and associated hardware issues, as both the core network UPS and the core network redundancy function have been successfully tested and utilized recently.
