"Full recovery is still expected to take several hours," AWS wrote in its latest update at 3:29 p.m. ET on Friday, adding that "efforts are slower than we had previously anticipated."
According to AWS, the outage was tied to overheating at a data center in its main US-East-1 region hosted in northern Virginia. AWS said issues were in a "single Availability Zone" in the region.
"We are actively working to bring additional cooling system capacity online, which will enable us to recover the remaining affected hardware in the impacted zone," AWS said in its 9:51 a.m. ET update.
AWS said it's working to resolve impaired EC2 instances, which provide virtual server capacity.
The AWS health dashboard first posted at 8:25 p.m. ET Thursday that it was "investigating instance impairments."
AWS had no additional comment.
