Nothing wrong with that if they fix the problem while you're null routed and restore service quickly.
If they just null route you and go back to drinking coffee, you need a new host.
Most hosting providers are not equipped to handle DDOS attacks. They can't stop a sophisticated DDOS attack. It requires special infrastructure and skills.
In my experience, they null route and suggest you wait it out.
