My site www.rapidlinks.co.uk was on shared hosting, it was fine, VPS, it was fine. 5 days ago I moved to a dedicated server, and since yesterday I have been facing large ddos attacks.

Is there any way to stop these? I am paying more for the dedicated now and experiencing more downtime :|
I think they keep changing the IP's so IP banning doesn't help.

You cannot do anything, unless you can contact your host as whoo said. When you contact them be prepared to pay 200-300+ a month for anti ddos hardware. There are no software firewalls that can stop any True DDOS attacks. so if some one tries to tell you so, its BS.
 
It all depends who's ddosing you..with what...and what method. it all matters, you did have to talk to your hosting provider.
There are some tools that can stop low threat ddos attacks but they will block legitimate traffic as well.

You do have to understand Anti ddos hardware COST a lot, and at a point they will give out if the DDOS attack is strong enough.

Talking about "true" DDOS attacks... hardware firewalls are able to filter the traffic only up to some certain amount. So when the "true" DDOS attack comes, they're useless anyway.

Also wondering how you found out that you're being DDOSed, because it's like the first thing people say when they don't know what's happening with their server.

It suddenly goes down, loads of connections from same ip? and tippie says the same thing.

Probably a botnet attacking you. Just wait it out...

Any idea how long it takes? Blocked a few more IPs today.

Well, if you're conviced that it's a DDOS attack, try this -> http://deflate.medialayer.com/

If it doesn't help, try HW firewall.

If it was really a heavy DDOS measurable in gbps, the data center would have nullrouted your IP a long time ago already.

Thanks, just installed (D)DoS-Deflate. Hope it works and sorts it out.
 
It may just be your host is a known target for DDoS attacks chances are your host has been on a few hacking forums in his past or is a acclaimed Anti-DDoS host that also will make him a target as people will be out to ''eXpose'' him if you site goes slow and doesnt denie acess this may be the case.
