Emerging new gTLD back-end player CentralNic today suffered a two-hour blackout of its registry systems, due to a “total power failure” at its data center.
Its registry, which handles subdomain services such as uk.com and gb.com and the ccTLD .la, was offline from 0930 to 1130 UTC this morning, the company said.
Even though the company has all the necessary backup precautions you’d expect from a total-uptime domain name registry, for some reason they failed to kick in, it seems.
The data centre is equipped with fully resilient power supply including N+1 redundant [Uninterruptible Power Supply] arrays and backup diesel generators, and the exact cause of the outage, and why the UPS and diesel generator system did not take over to maintain power, is not yet known.
The company is the named back-end provider for 60 gTLD applications, including a handful of dot-brands.
Coming so soon before ICANN starts the pre-delegation testing of registry providers, the outage is embarrassing to say the least.
