after some extended downtime, I rolled out the following changes to our instance:

• pict-rs was migrated to version 0.4 then 0.5. this should hopefully fix an issue where pict-rs kept leaking TCP sockets and exhausting its resources, leading to our image uploads and downloads becoming non-functional. let me know if you run into any issues along those lines!
• NixOS was updated to 24.11.
• the instance's storage was expanded by 100GB. this increased the monthly bill for our instance by €1.78 per month. to keep the bill low, I disabled an automated backup feature that became unnecessary when we started doing Restic backups.

I have one more thing I want to implement before our big Lemmy upgrade; I expect I should be able to fit it in tomorrow. I'll update this thread with details when I start on it.
