Yes, multiupload.com has been up and down the past day or so. But no worries, whenever I use multiupload I always include a couple of the mirrors it creates under the multiupload link. That’s what the “rs” and “mu” and “zs” stuff is about. So in the event multiupload disappears, the mirror uploads remain.
So I’m gonna continue using multiupload while it’s around, because it makes so many mirrors. Sharebee does this too, but the upload speed with them seems prohibitively slow.
