I just wanted to post this here because I want to help you all and hurt gen.xyz as much as possible. I had a .xyz domain through njal.la which I used to host jellyfin, homeassistant, and other basic things for friends and family. My domain recently became inaccessible without any notice. After a while of troubleshooting, I found that it had been reported to xyz as abuse, and they must have done zero investigation whatsoever before serverholding my domain. I thought about opening a ticket with xyz to get my domain back, but realized that I no longer wish to buy from some shitty company that will take down any site without warning. Bought a .com domain since they are somewhat reputable, and I would advise everyone here to never buy a .xyz domain. Angry rant over.
Since its servhold, you may be able to remove the offending content (for a short time, anything public-facing) and then contact reg.xyz to get it unsuspended. You’re right though that’s not very good customer service.
On a related note, it’s possible a misconfiguration allowed some of the contents or index to be shown publicly and it got caught in a search engine and was taken down in an automated DMCA sweep. I believe .xyz is an American registrar so have to respond to DMCA but could be wrong on that. I like to stay with any .TLD that archive uses… md, ph, etc.
