DNSSEC is the system that allows for cryptographically secure DNS. It’s all based on a root cryptographic key, maintained by the Internet Assigned Numbers Authority (IANA). Ever wondered where the root Key Signing Key is stored, and how it’s accessed? Four times a year, a ceremony is held where the root key is pulled out of a physical safe, and maintenance tasks are performed in front of a group of witnesses.
Such an event was scheduled for February 12th, but a teensy problem was discovered. One of the safes that holds the key media had a broken lock, and the root key signing key was inaccessible for a few days while repairs were effected. The open nature of IANA means that much of their operations are publicly reported, and you can even watch the key signing ceremony, which was finally held on February 16th.
