"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.
