To help its customers mitigate the effects of Distributed Denial of Service (DDoS) attacks against their networks, DE-CIX offers customer-triggered blackholing free of charge at all DE-CIX exchanges.

The key point of the blackholing feature is to allow network operators to announce the affected prefixes as Blackholes by using the BGP BLACKHOLE community.

In Frankfurt, there is a route server dedicated to blackholing announcements

available. More information on this service can be found online at https://www.de-cix.net/en/services/blackholing.
