FULL STORY ======================================================================

Microsoft Azure virtual machines (VMs) running the Linux distro Ubuntu 18.04,have been taken offline by a serious outage.

According to a statement from Microsoft , the issues began after Ubuntu 18.04 (bionic) VM users installed an update called "systemdversion 237-3ubuntu10.54".

After installing the update, the impacted users began experiencing domain
name system (DNS) errors. Will this affect me?

Microsoft says the issue, which now appears to have been fixed was confined
to this single Ubuntu version, however there was additional downstream impact on Azure services that leverage Ubuntu 18.04 (bionic) VMs including Azure Container Apps, Azure Database for PostgreSQL Azure Kubernetes Service, and Azure VMware Solution.

Ubuntu parent company Canonical did acknowledge the bug contained within the update, suggesting several fixes , however, it didn't mention the resulting Azure outagea.

Dr. Nestori Syynimaa, a Senior Principal Security Researcher at Secureworks commented on the incident in a Twitter post , saying: "These things happen
all the time and will happen as long people are using technology."

He added: "Not on this scale that often though".
