(Updates with Amazon's comments in the third and fourth paragraphs, and in the headline.)

Amazon (AMZN) Web Services appears to have suffered a major internet outage Monday, causing widespread disruption to dozens of websites, online games, and apps that the cloud service hosts, news outlets and monitoring websites reported.

Amazon Web Services' status page confirmed "significant error rates" in the US eastern region.

"We continue to observe recovery across most of the affected AWS Services. We can confirm global services and features that rely on US-EAST-1 have also recovered," Amazon told MT Newswires in an emailed statement.

"We are continuing to work towards full recovery for EC2 launch errors, which may manifest as an Insufficient Capacity Error. Additionally, we continue to work toward mitigation for elevated polling delays for Lambda, specifically for Lambda Event Source Mappings for SQS. We will provide an update by 5:00 am PDT," they said.

The problems began Monday morning and appeared to have impacted websites and apps linked to Amazon (AMZN), Snapchat (SNAP), Vodafone (VOD), and others, news outlets and tracking websites said.
