The Web We've Built (IN-PERSON)

This October, the Internet Archive’s Wayback Machine is projected to hit a once-in-a-generation milestone: 1 trillion web pages archived. That’s one trillion memories, moments, and movements—preserved for the public and available to access via the Wayback Machine.

We’ll be commemorating this historic achievement on October 22, 2025, with a global event: a party at our San Francisco headquarters and a livestream for friends and supporters around the world. More than a celebration, it’s a tribute to what we’ve built together: a free and open digital library of the web.

Join us in marking this incredible milestone. Together, we’ve built the largest archive of web history ever assembled. Let’s celebrate this achievement—in San Francisco and around the world—on October 22.

This year's celebration is a hybrid event. This registration is for in-person attendance at 300 Funston Avenue in San Francisco. Choose a virtual ticket to celebrate with us from afar!

Each ticketed attendee will receive a food ticket for one meal. Additional food items will be available for purchase.
