Posts in this community should be directly related to sh.itjust.works, not just Lemmy in general. With that being said, I think that the question has been answered thoroughly by the folks here.
I’ll take a look at our configs tomorrow 👍
Some maintenance done by @[email protected] caused issues. If you’re interested to find out more you can join us on #sh.itjust.works:matrix.org via Matrix. Long story short; the site image was preventing lemmy-ui from restarting after doing basic maintenance.
No major changes to the instance, this upgrade really did a lot to optimize performance. We’re still seeing some IO spikes here and there but overall performance is much better.
CPU usage has dropped by about half so far, so this is looking great so far.
Hey can you DM me your info, I can take a look at the email logs and see if anything funky is going on
A lot of bots were spamming the instance which was causing an IO bottleneck, and thus timeout issues. We’re looking into solutions to limit their impact, such as rate-limiting users. We’re trying to do it in such a way that it doesn’t impact regular users which is why it’s taking a bit longer.
The majority of these communities were cleaned up by @[email protected] tonight but if you spot any more you can DM him or also raise the issue on the Matrix chat that we have here.
We’re also working on implementing rate-limiting on our instance so these changes should make sh.itjust.works much less attractive to spammers.
There are many reasons to do so, such as wanting to use GPU acceleration or a better CPU than what your NAS or SAN has to offer.
