A series of power outages in the Swedish town of Katrineholm is not due to work on an Amazon Web Services data center, the tech giant said.

Local media reports claimed that a power failure at the facility, where the company is in the midst of upgrading the electrical infrastructure with utility Vattenfall, caused three outages this week.

“We are aware of the power interruptions in Katrineholm on the afternoon of Dec 16. During that power outage the generators providing backup power to our site came on and operated as expected," AWS told DCD in a statement.

"At the time of the power interruptions, we closely coordinated with Vattenfall to execute a planned re-energization of a utility supply connection at our site. Our initial investigation has not identified any fault within our site, but we continue to work closely with Vattenfall as they investigate to understand the wider power interruption that occurred.”

The exact cause of the outage is not yet known. The data center ran on its generators during the power outages, and AWS services were not impacted.

The company has operated a data center in Katrineholm since 2018.
