Microsoft Azure customers' virtual machines running Ubuntu 18.04 have been taken offline by an ongoing outage caused by a faulty systemd update.
Microsoft says in an incident report published on the Azure status page that these DNS issues only affect VMs running Ubuntu 18.04.
"Starting at approximately 06:00 UTC on 30 Aug 2022, a number of customers running Ubuntu 18.04 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," the company revealed.
According to the Azure status page, services currently impacted worldwide by this outage include Azure Kubernetes Service, Azure Monitor, Azure Sentinel, Azure Container Apps, and more.
Microsoft provides an additional workaround for affected Azure customers that involves rebooting the impacted Ubuntu virtual machines.
The company's Azure customers were hit by another global scale outage that took down Windows-based Azure VMs for roughly eight hours on October 13, 2021, due to resource migration issues.
