First, I'd find a better host that can mitigate a DDOS instead of just moving you to the "high performance server". Any host worth their salt should be able to put a stop to this unless it's using a very large botnet without repeating IPs, and even then it may not be that complicated depending on the nature of the attack. Why I say move to a better host isn't because of your attack, imagine they attack someone else on your shared server or on the network. If these guys can't mitigate your attack then you'll suffer when some other site is attacked as well.
Agreed. If your host is good, they should be able to quickly work upstream, even to the network carriers to shut this down. This is one reason why it's important pay a little more to go with a high quality host if you can't afford downtime.
