Your registRAR's availability doesn't stop your domain from being present at the registRY, but _if_ your DNS provider becomes unavailable you'll be thankful that your registrar is able to change your NS records with the registry.

- wlonkly 5y agoThere's three players: registry, registrar, and DNS host. The parts that affect your availability are the registry's nameservers and your DNS host. The registrar is the control plane for the registry -- if your registrar is unavailable and your registry and DNS host are fine, you're still up. If your DNS host is unavailable _and_ they're your registrar, then you can't make changes at the registry to use a different DNS host. But if they're unavailable and they're not your registrar, then you can still make changes at the registry to use a different DNS host (although you'll still have to deal with the two-day TTL on the NS records at the root). So the idea of using a different registrar and DNS host amounts to separating the control and data plane for your domain.
