0.19.3 Update

Edit: Upgrade went off without much of a hitch! Some little tasks left to do but we are now running 0.19.3. Seems like a lot of the federation issues have been solved by this too.

You will have to re-login and 2FA has been reset.

This update is scheduled to take place this weekend. No specific day or time because I am infamously bad at following those. I will try to minimize impact by keeping downtime to lower-traffic periods.

Ideally, there will be no downtime, but if there is it is likely to only last an hour maximum. During this time I will add an "under maintenance" page so you can understand what we are up to.

Feel free to join our Matrix space for more information and ongoing updates! My apologies for how long this took - I was in the middle of a big move and a new job.

Additionally, there may be small periods of increased latency or pictures not loading as I perform maintenance on both the backend database and pictrs server in preparation for this upgrade.

Proxy tuning

Earlier today, I identified the root cause of an issue causing annoying 502 errors intermittently. If you've ever had an action infinitely load until you refreshed the page, that is this issue. I deployed a fix, and am slowly scaling it down to stress test it. If you encounter an infinite loading occurrence or an HTTP 502 error please let me know!

UPDATE: Stress testing complete. Theoretically we should be equipped to handle another 5k users without any intervention from me

Image server maintenance

Hello folks! I am migrating the image backend to an S3-compatible provider for cost and reliability reasons. During this time, thumbnails and other images hosted here will be borked, but the rest of Lemdro.id will remain online. Thank you for your patience!

UPDATE: Image migration is gonna take a hot minute. Should be done in around 6 hours, I'll get it fully fixed up in around 7-8 hours when I wake up (~08:30 PDT)

UPDATE 2: It failed, yay! Alright, fine. I turned the image proxying back on. I am migrating to S3 in the background and will switch over when it is done. Any images uploaded in the next 8 hours or so may end up being lost.

UPDATE 3: Migration complete. Will be rolling out the update to S3-backed image storage in around 6 hours (~6pm PDT)

UPDATE 4: Object storage backend deployed! Thanks for your patience folks.

Upcoming server maintenance (10:30pm PT-> 11:30pm PT)

I'm sure you all have noticed the latency problems on this instance. Stage 1 of my 4 stage scaling roadmap is taking place tonight as I migrate the database to physically run closer to the machines running lemmy.

I will do a more detailed write-up on this later, but the gist is that each db operation required a new connection from lemmy, and that means a brand new SSL handshake since the db is managed elsewhere. Pooling would solve this, but lemmy does not handle a properly configured pg bouncer correctly in my testing. So the solution is move the database closer and within the private network to avoid SSL handshakes altogether.

TL;DR instance gonna go brrrr, downtime starting at 10:30pm pacific time tonight, should be done by 11:30pm
