I will be updating the instance to v18 at ~~20:00~~ 22:00 UTC.

See https://programming.dev/post/181191 for the changes

edit: Lemmy.ml updated and seems to have gone down. We're going to wait and see what the outage was caused by and then proceed from there.

edit 2: lemmy was down due to a ddos attack. We will upgrade at 22:00 UTC

edit 3: we had issues with the email setup getting overridden again. If you tried to sign up in the past 8 hours please try to just log in. If you can't, please message me (discord, matrix, or mastodon)

After logging a daily cycle of the system base load, could you post some before and after metrics for resource usage for comparison? That'd be fun to see.

Of course, though I think a single image just of the past few hours would demonstrate the difference pretty well lol:

Question for sysadmins: if you were looking at those metrics, without any context about an upgrade to production, what would you first suspect had happened?

Before cross-check unique visitor or page count remained steady, I'd have guessed the site got yeet'ed of every search platform or red flagged and blacklisted. 🚩💣☠️

Not a sysadmin, but I would assume that a load balancer or something had failed and prevented half of traffic from reaching the servers.
