treestats.net was unavailable for roughly 90 minutes today after going down while perming a routine upgrade. Services have been fully restored but please reach out on Discord if you see any issues.

Synopsis: Partially for my memory but also for anyone who's curious about the reason for the outage, here's a summary: Just prior to the outage, I updated the system TreeStats runs on with apt upgrade which is somethingn I do on a semi-regular basis. This upgraded packages for my deployment tool, Dokku, which resulted in a mix of incompatible binaries from different versions of Dokku for reasons I don't yet understand.

Rather than attempting to downgrade back to a known working version of Dokku, I decided to take advantage of the already-underway downtime to upgrade the operating system from Debian 10 to 12, upgrade Dokku from a 0.2x version to a 0.3x version (which I've been meaning to do for a while), and also upgrade MongoDB and Redis images up a few major versions each. With these upgrades now done, it should be easier to continue to do upgrades without downtime.
