High MS on Lordaeron

Hi, I have noticed that my latency has been very jumpy lately, this may be due to the server being full but it will go from 40 to 400 which is very annoying. I doubt it is on my side. I have been playing some other games today and had a constant MS of around 30. Any ideas?

19:11 Lordaeron is under massive DDoS attack again. Connectivity to the realm may be limited or unavailable. We are working to mitigate the impact.

Thanks, cant even login now :(
