For example, AWS's Mac machines frequently run into hardware failures. My current job runs a measly 5 mac1.metal hosts for internal testing, and we experience hardware failures on these machines a few times a year. Doesn't sound like a lot, but these machines are almost always completely idle, and we almost never get host failures for Linux hosts. To make matters worse, sometimes a brand new instance needs replacement before it even comes up for the first time, which is annoying because you are billed a minimum of 24 hours for these instances. People have been complaining about this for years and seemingly nothing is being done about it.
Right. When you see the curt, cranky and blunt responses of Hetzner engineers in the support threads, you know you are talking to an actual engineer who can fix your stuff and not some American-style 'We are sorry you are experiencing this problem!' type of support rep who cant do anything about it.
