Seven security experts have been entrusted with the key to reboot the internet in case of a global catastrophe.

The security experts have been given a key that can help them rebuild the DNSSEC (Domain Name System Security Extensions) system of trust for the internet if a catastrophe takes it down. The experts would have to physically carry the root key to a secret data center in the U.S. in order to reboot the internet. They essentially carry the ability to recreate the internet’s Yellow Pages database of web addresses.

The experts include Paul Kane, head of CommunityDNS; Norm Ritchie of Canada, Jiankang Yao from China; Moussa Guebre of Burkina Faso; Bevil Wooding from Trinidad and Tobago; Ondrej Sury of the Czech Republic; and Dan Kaminsky, chief scientist at Recursion Ventures in the US. They have been dubbed the “Seven Horsemen of the Web Apocalypse” or the “Fellowship of the Ring.”
