I am off for a couple of hours - if I can give some more information or ask my ISP for something later on please let me know?
What should I do to stop this in the future and get the restrictions off from my ISP?
Thanks Paul

If this is a synflood or any other ddos attack on his vps the tor server would not relay the attack and in and outgoing traffic would be vastly different.

Looks like DOS/DDOS.Is it even possible to DDOS over tor?
It's possible to (D)DOS any server using ping (or DNS, or any other UDP responder). All an attacker needs is the server's IP address, which is publicly available in the Tor consensus. Then they can attack the relay from the Internet.
There's no need to use Tor to tunnel the (D)DOS. In this case, Tor doesn't tunnel UDP, so it's unlikely to be the culprit.

The ISP didn’t mention - I would have to ask.
What I saw was that the traffic was up about linear from usually 30Mbits to above 100 Mbits over about 6 hours, bringing the CPU to 100% and dropping.
