Revisions are compiled and uploaded as they come, around 3800 (until 3801 iirc) the build was broken for Windows.
Some people (like me) do not upload new builds if nothing changed on Dolphin itselg (such as the Unittests, or the DSP Tools). If theres no links for particular revisions, waiting might be a better idea.
And the Hosting thing has been thru for quite a few times already, people choose their hosting for some reason, and so do the users; noone forces you to pick a particular one, IMO it makes things easier if you (for example) have an account on the given hoster.
