[LoverZPoint]

Hello,

well my vbulletin is Under attack i have Contact With my Dedicated hosting provider and i tried DDOS protecting sheild's ETC! everything my dedicated server provider says they can't protect from internel Server attacks Like this its attacking from script to mysql

then some one told me to use litespeed webserver !

i got some screen shots here!


< my site was enabled as you can see in screen shot more then 600 requets in Processing ... those request creating load and attacking to mysql and as you can see its 92% Load on webserver.

on 2nd screen shot i have disabled site i mean forum..





all request going fine to server over 4,000 per/second to 10,000 requests and 0.50 Load...

So what should i do now to stop this f**king Attack!!!
