Hurricane Katrina was the wake up call that New Orleans needed regarding survivability. Too long did people assume things would just be “okay” because “so and so” was handling it when they weren’t. Test your backups. Once you tested them, test them again, and then one more time.
Having your domain name registered with your IT company and not yourself is just a disaster waiting to happen. If they go out of business you have just lost intellectual property that can never be recovered. You can’t go “above” them and contacting the company they registered your domain with because it doesn’t matter since they still own your domain name.
It’s your responsibility to know if you own your domain name or if your IT company which is one hurricane away from being gone, owns your irreplaceable object which you is your domain name.
