- I am under DDoS. What can I do? 4 answers
first of all, I understand that it's better to have DDoS protections on data center level. But our DC is not ready to provide good quality of protection. So we thinking about using some external DDoS protections service.
I have googled several, like (sorry can not post many links):
- http ://blockdos.net/
- http ://www.armoraid.com/
- http ://www.blacklotus.net/
- http ://ddosprotection.com/

The general idea, is that you are changing DNS to point on DDoS protection service. They filter traffic for you, and then redirect it to your backend. So, it adds some small time overhead, but let you site be alive even under DDoS.
But it's really easy to write something on site. My question is: do anybody have experience with such service? Is it really helping against DDoS?
