I added a new product + locations to it 15 minutes ago, and despite the files being on a mirror (http://dm-download02.mozilla.org/pub/mozilla.org/firefox/nightly/3.6.4-candidates/build4/) there's 0% uptake The product in question is Firefox-3.6.4build4. This is blocking shipping 3.6.4build4 to beta users.
Nobody enabled "check now" on it, which means sentry wasn't going to bother looking for it until the once-daily overnight run tonight. The every-five-minutes job only looks for stuff with "check now" enabled. I just enabled it, and now you have uptake.
D'oh, sorry you had to called for this :(. Thanks Dave.
