The Global Switch data center outage in the London Docklands earlier this month has been traced to a cable end box on a UPS system. The power interruption lasted less than a second, but it took at least one customer two days to fully recover.
The 222 millisecond outage was caused by a fault in a high-voltage cable end box of a circuit breaker on one of the facility’s diesel rotary UPS units, according to an incident report by Claranet reviewed by The Register.
