App Store Problems?

Has anyone else noticed some strange issues with the App Store today? We had another app approved last night, but it isn't showing in App store searches yet (it's 18 hours since it was approved now).

Also, we made some changes to another app's description which aren't showing yet (these normally take 2 hours tops and it's been 8).

I don't think we're the only ones either, because if you look in the individual categories, there have been no apps released today in any of them (that I could see anyway).

Not seen anything anywhere from Apple that there is a problem, maintenance, etc - just wondering if anyone had any ideas, suggestions, etc?
