Amazon users affected by cloud outage

A giant outage of Amazon’s cloud-computing network in the US, which impacted large users such as media companies, was triggered by an effort to upgrade capacity, the company said Saturday.

The e-commerce giant’s Amazon Web Services (AWS) experienced a major glitch on Wednesday that even hit the publishing system of the Washington Post, which is owned by Amazon founder and CEO Jeff Bezos.

“The trigger, though not root cause, for the event was a relatively small addition of capacity,” Amazon said in the statement.
