Performance has improved after upgrading various OS packages, and upgrading kubernetes to more recent versions with performance improvements. Additional work is still ongoing to identify other areas where performance can be improved, but current performance is now better than it was.

The situation is now stable and services are working, but the performance is not back to the previous levels.

The problem seems to be tied to the kernel version we are running, which may not have full support for the new hardware we deployed.

We are working on updating our systems to a newer OS version and tuning the various system settings to ensure everything goes back to expected levels of performance.

Definite cause of the degradation has yet to be identified, however moving to more powerful nodes for the time being seems to have mitigated the issue. Sidekiq queues are still behind, but are no longer growing, and additional workers have been deployed to help it catch up.

A ticket has been submitted with Hetzner to see if this could be an issue on their side. Waiting to hear back.

This incident has been resolved.

The drive array on our main database server seems to be having issues.

You may experience some pages failing to load. Posts from other instances are also experiencing some delay as we are limiting their processing to get the database back at full speed.

This incident has been resolved.

The search feature is back after a recovery procedure, but we will deploy a new infrastructure for it tomorrow to avoid any future issues.
