Hello,

we will be performing the long awaited update to Lemmy 0.19.9 tomorrow.

We are planning for around 1 hour of downtime between 16:00-17:00 UTC on 16th of March.

You can convert this to your local time here: https://inmytime.zone/?iso=2025-03-16T16%3A00%3A00.000Z

You can find an overview of the changes in our previous announcement here and in the Lemmy release notes:

Update 16:50 UTC:

The upgrade was successfully completed at around 16:27 UTC, but we’re still fighting with some performance issues after the upgrade. Our database and the outbound federation container are currently using significantly higher CPU than expected, which is still being investigated to identify the root cause.

    It’s a bit of a shame we don’t see any significant new features in this release. Piefed seems to be developing at a much faster pace compared to Lemmy, which is a bit embarrassing tbh.

      considering that we’re coming from 0.19.3, this does still introduce quite a few bigger changes for LW.

          Do you think you guys could do a post on the underlying hardware/infrastructure of .world? I would love to see what it takes to run the largest Lemmy instance lmao

            in short form, we have HAproxy running on a hetzner cloud VM for Lemmy/Lemmy-UI, another HAproxy VM for the alt UIs, a VM for the alt UIs.

            for the main LW box, which runs lemmy containers, lemmy-ui, pictrs and a database each for lemmy and pictrs, we have a physical box with an EPYC 7502P 32 core CPU, 128GB memory and NVMe SSDs.

    This is the update that’ll break sync, right?

    Sad times, but I guess I’m gonna be deciding between boost and infinity tomorrow

      No it won’t. That’s the next major release, this is just LW catching up.

        partial breakage, the stuff that people on other instances have already been experiencing for a while.

        iirc there are still some additional issues with sync arising with the update, but it won’t be entirely broken.
