Amazon Web Services returned to normal operations on Monday afternoon, the company said, after an internet outage that caused global turmoil among thousands of sites, including some of the web's most popular apps like Snapchat and Reddit.
Still, Amazon said some AWS services had a backlog of messages that would take a few hours to process.
AWS hosts applications and computer processes for companies around the world, and the disruption knocked workers from London to Tokyo offline and halted others from conducting normal everyday tasks like paying hairdressers or changing their airline tickets. Users on Monday afternoon had complained of lingering difficulties using services such as digital wallet Venmo and video calling site Zoom.
The outage hit even banking services like Lloyds, Bank of Scotland and Halifax.
The root of the problem was a malfunction at Amazon Web Services, the tech giant's cloud computing division, whose infrastructure underpins millions of large companies' websites and platforms.
While outages affecting web platforms and services are nothing new, multiple sites going down in one single outage are somewhat less common.
