@kiwix Good golly. I've been using Hetzner for years and even just recently recommended them. Sorry you've had this trouble. I'd be really curious to know what their reason was. (Lost email or no, someone or some system _must_ have a record of why they took such a draconian action.)
@tjcrowdertech Yeah we've moved on now and are a bit sad about the whole thing, but it would be nice to know at some point and get closure.
