At 11:02am on 13/2/2015 our network provider had a UPS in an upstream communications rack fail during a self test during critical maintenance after a report of battery failure. Power was restored within minutes and services came back online at 11:07am. To avoid a recurrence, our provider will be moving comms equipment to a UPS with redundant modules and batteries. In addition to this, they will be splitting the Internet upstream connections across diverse power feeds.
