Container Groups: Intermittently failing to deploy successfully in UK South

We have been seeing an issue occurring over the past month or so where Container Groups are intermittently failing to deploy successfully in UK South, other regions do not appear to be affected. They seem to just time out after 30 minutes with not much information being provided in the deployment log. Any suggestions on what could be causing this behaviour?
