Any file downloaded comes back as not a valid zip file.

Hey just before the maintenance thing about 30 mins ago or so I downloaded extreme ui and opened it. When I came back to download again (had opened just to see which files were modded) it gave me an error saying not a valid archive. I tried a few other files and getting the same thing. So I went to a couple other sites and opened zip files just fine there. Did something get messed up?

Did a bit more checking. Files from All but WoW Interface come back as invalid archives. Those at wowinterface download and open fine.
