Namecheap. They do a good job.
Their support basically ignored any evidence to the contrary and let my domains expire and be sniped by other buyers.
EDIT: my motivation here is to tell you honestly what would strengthen your case. There is no upside for me in this conversation. I'm not affiliated with namecheap or any other registrar, and am merely offering my perspective: as a happy customer, I can be moved by other people's bad experiences, but they must be well documented. If you don't like hearing that, then ignore it.
It turned out that they are mostly a Ukrainian company, and when the war started the CEO decided to terminate “services to users registered in Russia” with only four work days notice.
I don’t know if any customer account was actually suspended. I also don’t know what “registered in Russia” means, is it nationality, residency, billing address, customer’s IP address or the A record. Some EU clients also received this letter.
I can relate emotionally. But this way to address existing customers, which have paid for their services, is whimsy and unprofessional. I also think that discrimination based on region or nationality is unnecessary broad. It certainly didn’t stop Putin.
Just to be clear, I believe Ukraine needs and deserves all kind of support to win this war.
To be fair I'd stay away from Cloudflare as well
