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.

    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.

      Huh interesting thanks! I’m pleasantly surprised at how little the “cloud” is part of it.

      Thought for sure it would be some flavor of cloud with a whole bunch of VMs or something like Kubernetes for scalability lol
