The front page seems to work alright most of the time but when I try to load any thread it either loads so slowly(sometimes like 30+ seconds) that I end up closing the page or I get hit with a Error 50x page that has been saying "Over the next few days, there will be a change in server infrastructure." for a long time.

Expanding images on the front page also tends to be slow.

Sometimes I get the 50x page when trying to do various things like posting a thread, upvoting, blocking and so on.

I feel like I haven't really seen anyone else mentioning it, is this just happening on my end, is it a known issue, if so then when can we expect things to get better?

Sadly it's quite effectively training me to not come here often since it rarely works.
