Azure APIM service unavailable after scheduled maintenance.
Last night one of our APIM instances (on the Developer tier) experienced scheduled maintenance and has not been available since. There is an error on the overview blade in Azure portal stating "Network connectivity check was not able to verify the status of 6 required dependencies." and another message in the portal notifications about "Failed to connect to management endpoint at <redacted>.management.azure-api.net:3443 for a service deployed in a virtual network." even though this is not deployed in a VNet, the Virtual network settings are configured as None.
I've been unable to find a root cause or solution to the issue. This is a resource critical to our testing efforts and I would like to restore functionality ASAP. I've attempted to scale up to Basic tier to see if that will restore the service but that is now causing the service to show the message "Service is being updated...".
I appreciate any help you can provide. Thanks!
