Internal Error Ugrading to IOS 5

Trying to get all my devices up to IOS 5 and I’m having issues with my iPad 1. No joy. I’ve tried 2 different computers, two iTunes versions (after trying to restore to a down graded iTunes and IOS on another mac I have) and then even the second computer with new new iTunes and code. two different USB cables. resets, reboots.

After reading more posts it turns out It’s a timing thing. I guess it’s related to the apple servers being too busy. I tried again this morning and it worked just fine. Keep trying.
