It started a few days ago that using the https://discuss.tchncs.de/ website (through the browser, default UI) is slow. It typically takes a few (maybe 5) seconds to load the front page, and often when opening a post, it takes another 5 seconds to load.
Writing comments and upvoting seems snappy fast though, so i suspect it has more to do with the UI and not the API.
Similar here. There are times when all attempts to open posts end in 504 errors.
Then after a few minutes it works again normally for a while.
