I assumed I'd missed warnings as well, but when I actually checked (after fixing the issue, because priorities) there were indeed no warning emails/sms/etc at all sent.
Literally, no kind of notification, warnings, anything at all. Due to this, and their support team being incredibly unhelpful during the outage, they're now on my personal blacklist for literally everything.
So instead of strongly recommended them, which I used to do, we've migrated 95% of everything off Hetzner and I'm hanging out for it to be 100%. And I warn others away from them at every opportunity. Like here. :)
We will not be returning to Hetzner. Ever.
I was using pre-charged account until waiting for a new bank account and credit card. I wasn't even hosting any VPS for a month or so, but Hetzner closed my account with no explanation, never got my money back. F*ck them, thieves.
Well that is indeed crazy, can totally understand your sentiment.
