What happens during a DDoS attack on my dedicated server?

A DDoS attack on your dedicated server does not automatically lead to a null route with us. If we do set a null route on an IP address, for example during a large attack, we do it by hand and you get an email about it.

What is a null route?

With a null route, we drop all traffic to one IP address. The attack then no longer hits the rest of the network. But that IP address is also unreachable for regular visitors for as long as the null route is in place.

What do you notice?

1. You get an email saying there's a null route on your IP address.
2. While the null route is in place, that address is unreachable.
3. Once the attack is over, support removes the null route.

Blackholing yourself with BGP

If you have a BGP session with us, you can request your own RTBH session. RTBH stands for Remotely Triggered Black Hole. With it you blackhole traffic to an address yourself, without waiting for support. Request it with a ticket.

More about BGP with us: see setting up peering with PlanetNode.

What can you do yourself?

• Keep an eye on your email. That's where the null route notification arrives.
• Suspect an attack but got no email? Open a ticket with the IP address and since when you've seen it.
• Is your server unreachable for another reason? See My dedicated server is unreachable: what can I check myself?
