Amazon Web Services said Monday evening cloud services had returned to normal after a daylong online outage disrupted thousands of websites worldwide, though AWS noted some services continued to have a backlog of messages.

The big picture: It's the biggest internet outage since an error at CrowdStrike caused a global meltdown that grounded flights and halted banking, leaving major platforms including Snapchat, Reddit, Duolingo and Coinbase down.

The "root cause" of the latest outage was an "underlying internal subsystem responsible for monitoring the health of our network load balancers" that are used to distribute traffic across servers, according to a Monday morning AWS post.

The latest: AWS said in a post Monday evening that all of its services had "returned to normal operations."

Some services, such as AWS Config, Redshift, and Connect, would "continue to have a backlog of messages that they will finish processing over the next few hours," per AWS.
