If that was the case I think it would have made major news

Datacenters and high availability systems have redundans built-in on many levels. Its not very uncommon that redundans is activated on storage, network or other levels. It takes a disastor to impact power on datacenters to the point where both fails.

Back in the day when I was involved in Disastor tests we joked with the scenario of both datacenters failing, because if that was the case pur country would be in a disastor situation
Look at it from another direction - 99.9 percent availiable datacenter would still be unavailiable 1 day per 3 years. Despite how improbable it may seem that a datacenter would fail, especially to a specific cause (power), between the many datacenters it would occur fairly regularly.

p.s. my view is formed by operations of a major telecom and other services provider.
