WordPress.org will be undergoing some maintenance starting Wednesday, October 24, at 11AM Eastern (1500 UTC), which will result in intermittent downtime (physical servers are being moved) over the course of a few hours. (This post originally said Tuesday, October 23, because I wasn’t paying attention to what I was typing.)
Ideally, api.wordpress.org and the wordpress.org website (including this blog) will not go down, but access to all Trac installs and SVN repositories will be interrupted at some point. The goal is for error messages to be shown.
I will update this post once the migration is complete.
