Since when is "let's skip the basics" asshole vibes? It's a waste of time for them and myself to cover all the basics, which I've already gone through.

"did you check the power cord?", " did you reboot it?", "Is it actually on?"

Yes, I'm not tech illiterate. We don't need 5 back and forth emails over the course of a few days to get down to something helpful. Give me the helpful stuff up front. Sometimes this stuff is time sensitive and these support people are costing companies a lot of money due to unnecessary downtime. I used to work for Disney+ and we had servers that died all the time, we'd email Dell or SuperMicro and tell them what the issue was, and then we would spend days or weeks of back and forth doing things we already tried, or things we know wouldn't fix the issue before they finally decide "ok let's replace it". A few times their suggestions even bricked our servers and made the problem worse! We'd say that there was a CPU issue on a server that started crashing and the IPMI logs and Linux itself would point to a faulty CPU or RAM. They told us to flash a new EFI, we would do so, and great now the server doesn't power on at all instead of just crashing occasionally.
