Power outage affects services like Slack, Imgur, and the Epic Games store for some users. Some Slack users unable to view or upload images and work management tool Asana also hit by the outages.

At 9:13am et, Amazon said it had restored power to the affected servers. By 12:28pm et, it had’restored underlying connectivity to the majority of the remaining’s systems.

At 7:22pm et, Amazon marked the issue resolved. That restoration did n’t necessarily fix everything for all of the servers affected.

Some EC2 instances and EBS volumes experienced a loss of power in a single data center within a single availability zone (use1-az4) in the US-EAST-1 region.

At 4:55 am PDT, power was restored to EC2 instances and EBS volumes in the affected data center. Some of the underlying hardware experienced failures, which needed to be resolved by engineers within the facility.

Engineers worked to recover the remaining EC2 instances and EBS volumes affected by the issue. By 2:30 PM PST, we recovered the vast majority of EBS volumes.

For customers still waiting for recovery of a specific EC2 instance or EBS volume, we recommend that you relaunch the instance or recreate the volume from a snapshot for full recovery. If you need further assistance, please contact AWS support.

Slack said its services were’experiencing issues with file uploads, message editing, and other services’. The problems constituted a’major outage’.

Of the affected services, it appears that they are largely back online, even as Amazon’s restoration continues. A slack page tracking the connection issues marked the problem resolved around 3:13pm et.

It’s the third time in as many weeks that problems with AWS have had a significant effect on online services. Two incidents earlier this month involved taking out streaming sites like Netflix and Disney plus.

Some users are unable to access services entirely and others merely experiencing intermittent fault. Downdetector.Com shows reports of issues with the platforms mentioned above.
