Guys, need some help here. I have been running a couple successful sites, and lately they have been under attack. I believe they are coming from our competitor in adwords, since we took his #1 spot. Anyway, they have been doing DDOS attacks against our server so I hardened it the best I could. This is a dedicated server, mind you. We are still getting flooded and hacking attempts. We then took it to another hosting company but they suspended our account saying they were getting a DDOS attack on their entire subnet. Do you guys have any experience with good hosting providers that protect against this crap? Supposedly Hostgator does, but I don't believe them. Thanks!
Thanks. I'll take a look at them. Supposedly http://www.websitesource.com/ has DDOS protection too but this ended being false.
http://www.secureservertech.com , last year I was moving around for ages trying to keep my site online because of DDOS attacks. I've been with these people for a year now, I've had around 1 hour of downtime in the last month. Prices are decent and protection and service is good
Stopping DDos should not be that difficult, I would said. Your web hosting provider should help you to filter out the IP which attacks your website.
there are some important things that you have to take into account before considering an option for ddos protection. first, what is the scale of the attack? Is it something major or not? If it is not a massive attack, maybe your ISP could be of help to you or maybe you could change from Apache to Litespeed if the case is you're using Apache. If the attack appears to be a huge one and if it damages your company's reputation and inflicts great income loss then the option to choose a provider specializing in delivering ddos protection and mitigation services is the best choice. Mind you that the companies that offer cheap services most often are incapable of handling the malicious traffic of sophisticated attacks. So if you go for that option and if your business requires that move make sure that you do not go for the first company that offers you a cheap service. First they will most probably not be of help to you and it could turn out in the end that it has cost you even more than the more expensive ones and the ones that really solve problems.
If its DOS attack then usually you can mitigate them using different simple tools available on the net. But if its ddos attack then i would suggest to use some hardware firewall like Cisco Ddos guard provided by Softlayer. Go with softlayer and use netstat to find if there are scattered attack on your server, and if it is, then just open a ticket with IPs which needs to guarded to reduce the ddos attack. This should do the best. Though, i have seen, Cisco guard doesn't work perfectly in an event of DOS attack where One IP creates lots of connections faster and frequently, in such cases use a modified version of Dos-Deflate so that it scans only for established connections. That should sort your ddos problem Good Luck
