The new IP address is 37.187.55.214 so if you ping that address and get something else then your system has not seen the DNS changes yet.
Again I am very sorry for all the trouble, however even YPool has been taken down by DDOS attacks recently and they have a much much greater investment in their infrastructure. It is not a cheap problem to solve. While the advice is appreciated small plans like the 20Gbps plan posted a few pages back are insufficient. Though if this provider does not work out I will probably contact them for a quote just to see how much they would charge for a larger plan.
Amusingly this new provider has already notified me that the host is under attack and they are mitigating it. The attack picked up on the new host quite fast, I was not sure if it would be going direct against the IP or the DNS entry, looks like DNS lookup then. This is encouraging though as the attack is continuing but this new providers DDOS protection is handling it.
I am going to crash for the night and see how things look in the morning though sadly morning is only a few hours away now.
everything will be ok.
