From August 15th, 2023 to August 24th, 2023 Red Planet Labs operated a Twitter-scale Mastodon instance at https://mastodon.redplanetlabs.com to demonstrate the power of our programming platform, Rama. The source code for the instance is only 10k lines of code and is open-source on our Github.
The instance ran with 100M bots posting 3,500 times per second at 403 average fanout to demonstrate its scale. During the course of its operation, the instance processed 2.66B posts and made 1.07T timeline deliveries.
