They blocked several critial IPs of mine without any warning, their support had absolutely no idea what the problem was and refused to unblock my IPs until I could convince them I'd solved the "problem" (which was an extra mac address appearing on one of my router addresses -- not an actual problem) and cost my business about 10k in the process. The email chain was... painful.
I've never had such a bad experience with a host before. YMMV of course, but I'm back on OVH and life is easy again...
this was posted here. I was intrigued but have not tried it (because my software relies on java 11, which is not on OpenBSD)
