Attack on ISNIC website

A large scale DDoS attack was performed on the ISNIC website tonight, and it affected the web, EPP, WHOIS and RDAP services.

The first warning was triggered at 01:45 tonight and on-call personnel started analyzing the problems shortly after.

The attack was not fully averted until 07:33 this morning and all services were then up and running without problems.

We're still analyzing the attack and identifying weak points that can be strengthened to better endure attack like this in the future.
Leave a message and we will reply as soon as we can.
