Microsoft Azure suffered from an outage yesterday, November 5, while Amazon Web Services (AWS) seems to have also briefly experienced issues.

The issues come after both hyperscalers experienced problems in late October.

Microsoft said in a 22:49 UTC status report yesterday that its West Europe region, located in the Netherlands, was experiencing a "thermal event" and that some users might experience "service disruptions or degraded performance" across multiple services.

As reported by The Register, the thermal event impacted Microsoft's data center cooling systems, which "led to a subset of storage scale units going offline in a single availability zone."

The status report noted that resources in other availability zones may be impacted should they "depend on these storage units."

Microsoft estimated that the issues would be resolved in around 90 minutes. At the time of writing, the Azure status page lists no active issues.

A previous Microsoft outage on October 29 was much more extensive, bringing down several websites, and Downdetector showed thousands of reports of issues globally. That outage was caused by "DNS issues."

AWS, meanwhile, also seems to have suffered an outage on November 5. The cloud provider's parent site, Amazon, saw more than 6,000 incidents flagged on Downdetector yesterday, as reported by Reuters, with some AWS users also flagging issues.

The AWS outage seems to have primarily impacted US users and seems to have since been resolved. "AWS services are operating normally," a spokesperson for AWS told Reuters.

AWS suffered a major outage on October 20, bringing down several websites and platforms that were using its East-1 region in Northern Virginia.
