a few minutes ago there was a massive attack on your server. We therefore route the affected IP address 37.X.X.X via our free DDoS filter. This filters all packets that cause the DDoS. So the services of your server that are not attacked remain accessible. Due to filtering, packet runtimes may be somewhat longer.
We check at regular intervals whether the attacks have subsided. Once this has happened, we will route the IP address 37.X.X.X directly back to your server.
Below you will find log extracts representing the attack patterns:
