Update by our Admin at todon.nl:
"The attack on your server is performed with ~9500 Mbit/s and 2580000 data packets per second. this is a large scale professional DDoS attack, and we had to temporarily null-route the attacked IP to protect our network. Your Server will be accessible again, as soon as the attack is over of course."
I'm a Todon.nl mod in direct contact with the admin at all times, so feel free to contact me.
