Amazon says that Amazon Web Services, a cloud computer service that powers many of the internet’s most popular apps and websites, has “fully recovered” from a major outage that disrupted online activity around the world for several hours on Monday.

Late Monday afternoon, the company said in an update that all AWS services had “returned to normal operations.”

According to Downdetector, a website that tracks online outages, users of apps such as Snapchat and WhatsApp and major websites, including Amazon, began reporting service disruptions shortly after 3 a.m. ET.

Amazon said that it was “investigating increased error rates and latencies for multiple AWS services in the US-EAST-1 Region” and that it was actively working to resolve them.

By 6:35 a.m. ET, the company said that the issue had been “fully mitigated” and that most services were working normally. But the company added that there could be some lingering delays.

“Some requests may be throttled while we work toward full resolution,” Amazon said.

Amazon Web Services, along with Google and Microsoft, provide most of the world’s cloud computing infrastructure.

Among the apps and sites reporting outages on Monday:

• Amazon

• Amazon Alexa

• Coinbase

• DoorDash

• Fanduel

• Fortnite

• Google

• Grubhub

• Microsoft Teams

• The New York Times

• Pinterest

• Reddit

• Snapchat

• Spotify

• Starbucks

• T-Mobile

• Verizon

While most of the apps and websites that were experiencing disruptions are working normally, Amazon said in an update that there could be some lingering delays.

“Some requests may be throttled while we work toward full resolution,” the company said.
