Microsoft Azure customers are experiencing issues on Ubuntu 18.04 virtual machines.

The cloud company said that users are experiencing DNS errors when trying to access resources, with the issue impacting customers around the globe.

"Starting at approximately 06:00 UTC on 30 Aug 2022, a number of customers running Ubuntu 18.04 (bionic) VMs recently upgraded to systemd version 237-3ubuntu10.54 reported experiencing DNS errors when trying to access their resources. Reports of this issue are confined to this single Ubuntu version," Microsoft said in an Azure Service Health post.

The bug is a known issue, with Microsoft pointing customers to this link for a possible fix.

"An additional potential workaround customers can consider is to reboot impacted VM instances so that they receive a fresh DHCP lease and new DNS resolver(s)," Microsoft said.

The Azure status page shows issues in virtually all Microsoft cloud regions. The issue is also impacting Azure China and Azure Government.
