We do offer DDoS protection on all our nodes. We have often received attacks on some IP's.
Please note we will try our best to mitigate an attack with well configured firewalls. The protection provided by our DC is at 11Tbps total capacity. Nevertheless, it is sometimes possible to bypass our firewalls.
We will only null route your virtual machine IP if and only if it affects the overall performance of the nodes considerably. This will only happen if we are unable to mitigate an attack on your machine. Please take into consideration we will do everything in our power, such as changing and proxying your server IP before that has to happen.
