Tomorrow there should be a small update to the Study pages adding paging of the Shared Stories list. This along with a database tweak hopefully will make a noticable improvement to the response times of the Study pages.

The website has to be disabled for a short while because it requires an update to a table of the database that contains millions of rows (your kanji stories !). You can tell the website is being updated, rather than having some kind of trouble, because it will redirect to a maintenance page.
