@sezzy , i can provide my own reply , its useless to provide a reply in my place if you do not even know the reason and i basicly hate it if you post a wrong reason (specialy if you post datacenter moving ... )

anyway , here is your reply

email wont work as my main site wont work ( dns ...)

but to provide a quick answer
there are a few server problems at this moment
for 1 of other reason does it seems to crash the complete server when apache is getting more then 120 requests at the same time
it seems to came all from 1 site but the hard part is to prevent that that site can bring down the server

i was thinking i fixed it yesterday (as it was fine yesterday and the day before) but suddenly my datacenter even needed to reboot my dedicated
after the reboot was everything back fine , went to sleep at 7.30 am and then later that day apache + dedicated crashed again for unknown reason (need to check logs and other things to solve it )

in meantime i know where the 2 biggest conections are coming from and i am solving the problem (and why apache keeps getting more then 120 - 256 requests all the time )


to explain it realy simple
apache and mysql get overloaded my mass conections from differend ip's
that use a lot of cpu/mem and let the programs crash
if it does not crash , then the ram get overused and then the dedi just crash

howto solve ??
find how it comes that apache got that many conections and tune the firewall why it does not block those users with that many conections
tuning apache so it does not use all the ram under heavy load
tuning mysql to return a error value instead more data under to heavy load
and a lot more of tuning to optimise the settings

or my final solution if nothing else is working anymore , moving the user who is responsible for those mass conections ( as they are from 1 - 2 sites of the same user )

hopely this explains the problem to you and sorry that it goes down a lot those days ( i hate it to , solving it)

so your basically getting spammed by someone, could that someone be trying to shut you down? since they have successfully crashed your systems more then once.

[PowerChaos]

it has nothign to do with me
it has to do with a client that host specific things (no more comment over that )

and the reason the servers where going down is because apache that was crashing all the time

seems that it came from a anonymouse proxy ( british proxy) and they are basicly spamming with more then 800 conections at the same time (also called DDOS)

problem with that proxy , because that ip is all the time differend does your firewall not block it (as it does not trigger max conections per fixed time)

so its just a mather of finding out what ip's are from that proxy and what ip's are returing all the time so you are able to block those proxy's

at this moment i am getting more info from the company who provided that service, so i can block all ip's from that proxy service , and in meantime the problem should be solved to (most proxy's are blocked , so no mass conections anymore)

sorry agian for the trouble
