First of all, I love you, slrpnk admins. You handled it all like champions! Happy to have you back.
Someone said in one one of the matrix chats during the outage that the fact that this instance is selfhosted and went down is like true experience of a solarpunk world; there won’t always be power and that’s okay!
Just wanted to write it down in a post since that message was so spot on.
There’s a page for info on horizontal scaling Lemmy here: https://join-lemmy.org/docs/administration/horizontal_scaling.html
It does seem to be out of date (for one, it mentions that pict-rs can’t be horizontally scaled due to the sled database, but pict-rs now supports postgres so maybe that has changed.
I know larger instances run a separate federation container and many instances (including mine) run multiple lemmy-ui containers for the front end, but as I understand it the Lemmy backend can only run as a single service.
