After this whole register fly fiasco, I've decided to transfer a domain to Namecheap. Unfortunately this is my highest earning site. Will my site be inaccessible while the transfer takes place? If so any rough idea how long?
It does not depend on the transfer or registrar but in your hosting service. If your site is up there is no downtime associated. although it might take up to one week before transfer occurs. Your new registrar service will not let your DNS go down during the process regardless whom you choose as your new registrar service
