Amazon.com Inc’s widely used cloud service, Amazon Web Services (AWS), is experiencing an outage, the company says.

“Kinesis has been experiencing increased error rates this morning in our US-East-1 Region that’s impacted some other AWS services. We are working toward resolution,” an AWS representative said in a statement.

The outage has affected several companies including video-streaming device maker Roku, Adobe’s Spark platform and picture/video hosting website Flickr, according to their recent posts on Twitter.

Amazon’s cloud services business is thriving on higher demand from companies switching to virtual offices due to the COVID-19 pandemic.

Sales from AWS, which sells data storage and computing power in the cloud, rose about 29 per cent in the third quarter.
