Another power outage has hit Amazon Web Services (AWS) data centres. For the third time this month, AWS grappled with a power outage in its US-EAST-1 region.
The issues started around 7:30 a.m. ET and the knock-on effect of these issues continues to plague the service as of 1 p.m. ET, as AWS continues to report issues with a number of services in this region, specifically its EC2 compute service and related networking functions. Most recently, the single sign-on service in this region also started seeing increased error rates, according to a report in TechCrunch.
“We can confirm a loss of power within a single data center within a single Availability Zone (USE1-AZ4) in the US-EAST-1 Region,” the company explained in an update at 8 a.m. ET. “This is affecting availability and connectivity to EC2 instances that are part of the affected data center within the affected Availability Zone. We are also experiencing elevated RunInstance API error rates for launches within the affected Availability Zone. Connectivity and power to other data centers within the affected Availability Zone, or other Availability Zones within the US-EAST-1 Region are not affected by this issue, but we would recommend failing away from the affected Availability Zone (USE1-AZ4) if you are able to do so.”
“The issue has been resolved and the service is operating normally,” AWS said. On December 7, the same US-EAST-1 region went down for hours due to a networking issue. Then, on December 17, an outage that affected connectivity between two of its West Coast regions took down services from the likes of Netflix, Slack and Amazon’s own Ring.
This development comes close on the heels of AWS stating the resilience of its cloud services at its recently held re:Invent conference earlier this month. Several apps and websites, including those of streaming service Hulu, office messaging app Slack and Epic Games, were down due to the outage.
