Ubuntu update causes server downtime on Microsoft Azure

Ubuntu developers released a patch for a core component, systemd, morning that caused problems for servers hosted in Microsoft’s Azure cloud platform on Tuesday morning.

The issue was reported by South African Ubuntu user “Pieter” (a.k.a. “diepes”) just before 07:00 on Tuesday.

According to the report, the systemd’s update to version 237–3ubuntu10.54 broke Domain Name System (DNS) functionality, causing connectivity problems for Azure virtual machines

Yup, that pretty much sums up my experience with systemd-resolved
