You can also check out gigeservers.net, staminus.net, and awknet.net. Even though I think those providers will auto null attacked IP's depending on the level of inbound ddos
I know Staminus and yes they are good, ddoswiz and dragonara as well. But no one can beat blockdos.net .I've tried them before and they are truly the only one that is 100% trouble-free. Almost 100% uptime even when the server was under attack. I recommend you to use blockdos.net if you want a risk-free dDoS protection.
There are many level of ddos from mild to high ddos so different levels of ddos requires different anti ddos hosting services and also remember hosting on anti ddos shared hosting means your website will also under ddos attack caused by other websites which have hosted there first before your site, it means it's not better if you host on non anti ddos server
It does not matter the date, but this important thread should be updated. Current Antiddos hosting situation is different now, some has too many malwares, some change from antiddos hosting to just antiddos solution like Blockdos and many small antiddos hosting has merged with the older antiddos hosting. And be careful many so called antiddos hosting is just only ex IRC hosting with bigger bandwidth.
