Store down?

I am trying to use the iTunes store as well as upload a Nike + workout. I keep getting a message saying that the store is down...to try again later.

Anyone else having this problem?

 

That's what I was affraid of...I am temporarily stationed somewhere and the base has a firewall. That means that I won't be able to upload my nike + workouts for the next 3 months.

Does anyone know the port that nike + uses, so I can try to get them to open it?

Thanks.
