Observing the ceremony

The key signing ceremony is a public event, and you are welcome to observe. Due to space constraints, only a small number of persons are able to participate as observers at a ceremony in person. We also broadcast ceremonies as they happen, and will provide recordings after the ceremony is concluded. Prior to observing a ceremony, we recommend you review the ceremony materials (i.e. the draft script) in advance.

In Person If you wish to attend as an observer in person, this must be arranged in advance. Priority is given to those that have a formal role in the ceremony, and then on a first-come first-served basis. This ceremony will be held in El Segundo, California, USA, and observers must meet all costs in travelling to the ceremony. Requests should be submitted at least 45 days before the ceremony (i.e. by 2 June 2024)
