The instance has been updated to version 0.19.4!
You can see the official release post and notes here: https://lemmy.ml/post/16585359?scrollToComments=true
Since this update required some manual intervention anyway to update the database version, I took the opportunity to perform some overdue server maintenance and upgrades.
I have migrated the server to a more powerful configuration, and changed the way image files are being stored and served (object storage as opposed to filesystem storage).
I am also aware of some federation issues that have affected this and other instances. I am not sure whether this upgrade will deal with these problems automatically. I will be looking into it and hopefully will implement some solution soon.
Sorry for the downtime experienced in the past few days, but hopefully with the more powerful server the experience will be smoother and will remain so for a while.
For other admins and users interested, this is a bit of information about the server
The previous configuration:
Hosting provider: serverspace.io
8 GB RAM
4 Core CPU
50 Mbps network
400 GB SSD
Cost: $55 / month
The 400 GB SSD was being used to store both the server's database and the image files, and this component in isolation had a monthly cost of $36. I have migrated the images to an object storage provider ($6/month for 500 GB), and used the resources previously used for disk space to increase the other parameters. The new configuration is a lot better and less expensive.
New configuration:
Hosting provider: serverspace.io
Object storage provider: contabo.com
16 GB RAM
6 core CPU
50 Mbps network
100 GB SSD
500 GB Object storage
Cost: $47/month
Thanks a lot to the lemmy and pict-rs devs for the hard work they put into developing the infrastructure!
Hey @RobotToaster@mander.xyz , @lvxferre@lemmy.ml , and @Shdwdrgn@mander.xyz - we are now in sync with lemmy.world and the database under much less stress. This seems to have fixed the problems that I observed on my end. Are your problems also resolved?
I just resubbed to the communities that were causing issues and it looks like everything is working well now, thanks.
Ah! It looks like it JUST fixed it, I had checked about 15 minutes ago and still couldn't get my subscribed list to load, but it does appears to be loading up now. I'll reset my preferences and keep an eye on it through the day -- hoping for the best!
It should have been fixed about 13 minutes ago! Thanks for checking! If problems persist I will try to fine-tune the database settings as suggested above.
There was a brief outage soon after I left that last reply, assume you were doing another round of maintenance at the time, but otherwise it's still looking good from here.
Ah, thanks. I think that was when I reboot the instance to change a setting that controls how post thumbnails are generated, as the new setting was failing to generate thumbnails for many posts.
