RIPE NCC network affected by the DDoS attack

Dear Colleagues,

Starting from 14:00 UTC today, 27 February, RIPE NCC network suffered a
large DDoS attack. It was a distributed ICMP echo attack.

The attack caused various congestion related problems for the RIPE NCC's
network, to the extent that our BGP peering sessions were affected, and
non-ICMP traffic was being randomly dropped.

The attack was successfully mitigated with cooperation of our peer
networks at AMS-IX. Network condition returned back to normal at 16:30 UTC.

As a result some of our services, including (web), (RIPE Database), (DNS) and (FTP)
were not accessible during this timeframe. Now all services are back to
