A string of power problems beset Amazon Web Services last week at its Ashburn, Virginia data centre. Culprits ranged from human error to a vehicle crash that took out a power pole. The company says it's plain bad luck, that it's working hard to keep things running smoothly, and that users should also protect themselves using AWS tools and services.

"Sometimes these incidents just bunch themselves together, and there's no explanation for the timing on these. We take operational performance very seriously," Amazon spokeswoman Kay Kinton said via email. Kinton said the events were unrelated and that the failures affected a small subset of a single Availability Zone each time. "It's important to remember that we provide customers the building blocks to be resilient to any failure in a single availability zone," she said.
