We have Ddos attack on our website, 75000pps. We need expert to fix this or help to fix this partially as we can ignore traffic from most of countries and we're interested in USA and a few EU countries traffic only. so probably some GeoDNS solution or checked script to stop traffic from other countries or any other ideas.
The experts from DDos protection Staminus.net works on our site and it works fine now. But we're worry that attack can raise and we should pay more later. So we have the idea to forward part of traffic, except of USA and some EU countries, to second our server that will be nullroute. Seems this can be done using GeoDNS. Or probably redirect like traffic using other methods, setup own DNS etc. Then will forward to Staminus to filter traffic from important countries only. We have 2 Linux servers to try and test things. And we need expert that can consult and do this job for us.
