We had an instance crash (first time), once we were bestowed the honor of submitting a ticket after an hours of downtime (to which the clock only started an hour after the instance went offline, we were able to solve the issue ourselves, and closed the ticket an hour after submitting it... to which a couple of days later we received a response asking about the issue.
Ah I had that experience on Azure. With aws we have paid support so when we have issues and raise critical tickets they respond in ~20m but azure. When they were still doing sql server as a service I lost access to my database. Support told me there was no problem. The azure insiders forum said others were having issues. The support wouldn’t even acknowledge I couldn’t access the database. 2 days later I finally got access again randomly. I never got a response to why this happened. I’m just Glad this was a non production application for some contract work but they ended up wanting to go aws over the experience.
I Guess at the end of the day we all experience different levels of support from all these providers.
I got some support from Azure a few months ago asking about DTU spikes, more of a shot in the dark than hoping for a good answer, but got an extremely good, knowledgeable woman go through it with me within a day. We only spend a few thousand a year at the moment.
I may hate their admin interface, but their support was top notch in my experience.
