  • No off the shelf forum software has ever been proven at that scale. There’s far more at play than just “storage and bandwidth”. At that scale every operation has to be carefully designed. A table or index scan on any remotely common function in this setting would cripple the entire DB server with even one row per user in the table.

    With 70m monthly active users, we’re in stack overflow and reddit 2012 territory. Nothing off the shelf, build your system yourself, nothing ready to migrate to at present. Even just the reads become a challenge, you’d need a CDN, load balancing, all the modern bells and whistles.

    An off the shelf forum would be fine if it was just a few tens of thousands of users.

    The biggest phpbb forum ever, for example, was Gaia online which was a heavily customised and rewritten phpbb that capped out at 90000 concurrently online users and 26 million registered users in total.

    These protests are the largest in human history and just comprehending the scale is a struggle for most, normal systems just do not cut it.
