ICANN name servers come under attack

ICANN’s primary name servers came under a distributed denial of service attack, the Org said earlier this week.

The incident appears to have gone largely unnoticed outside of ICANN and seems to have been successfully mitigated before causing any significant damage.

ICANN said on its web site:

ICANN was subjected to a Distributed Denial of Service (DDoS) attack targeting NS.ICANN.ORG. This event did not result in harm to the organization. It was mitigated by redirecting traffic flows through a DDoS scrubbing service.

ns.icann.org is the address of ICANN’s name servers, which handle queries to ICANN-owned domains such as icann.org and iana.org.

The servers are also authoritative for Ugandan ccTLD .ug for some reason, and until a few years ago also handled the .int special-purpose TLD and sponsored gTLD .museum.

ICANN did not disclosed the exact date of the attack, nor speculate about whether it was targeted and why it might have happened.
