We once had an error with Azure MySQL and AKS, where it would just stop dropping packets with basic instance types. Support could never fix it, we ended up just upgrading to standard because that worked.

I will say this - the manager of the team at Azure did comp our upgrade, because they couldn’t figure out why it was happening. I tried very hard to get our project off Azure, but because it was negotiated as part the Enterprise Agreement with Microsoft, it was “free” so the CTO wouldn’t budge. I assume this is how many people end up needing to deal with Azure.

It took quite literally months to get the issue escalated to someone who could do anything about it, and as far as I know it’s still broken, although it’s scheduled to be fixed this year. We had to pay for this “support” too. We worked around the problem in the end, but still.

I never understand it when I see people say this about Azure. Did you ever try creating a support ticket through the Azure portal? My experience has been nothing but stellar. They respond very fast, they provide very in-depth expert knowledge, and they seem to be quite thorough, escalating any issues if needed. This is my experience with creating tickets for various organizations, both big and small.
