I've recently been experiencing significantly longer loading times on the wiki than usual, both before and after the unplanned downtime. Everything except the login page (which is cached by my browser) takes a few seconds to load, with long pages like the main page, GregTech and especially the recent changes taking longer than short pages - main page takes maybe 3 sec, GregTech 5, recent changes more than 10. The long recent changes loading time appears to be partially due to the login redirect I have set up, accessing them normally from the nav menu is slightly faster (5 sec?).
I'm using the regular site, not the nocache version. This is happening using multiple browsers and on different internet connections and providers, so odds are that this is a server-side thing.
PS:
Now the site stopped responding at all, including nocache and ATLWiki.net. The forums work fine (duh).
