We have an App Service Plan in North-Central US. It has 20 Apps and 9 Slots. We have Autoscale Scale Out configured to go to 2 instances every day during our busy times (7am-9pm) each day of the week. This has worked for many months. On June 4 it started failing (every minute) with a “This region has quota of 0 instances for your subscription. Try selecting different region or SKU”, so always just 1 instance. I opened a support tag on June 7 and was pretty much ghosted after a couple days. I opened another support ticket on June 18 and while it garners some attention, no remedy. The support process mostly consists of me re-sending the same Azure Portal screenshots of the errors and the support person saying “the Product Group Team is working on it”. So still no Autoscale for 3+ weeks now.
