Apple Store outage related to larger 'net issues?

As tweeted by TUAW earlier this morning, the online Apple Store was down for hours and finally came back up a few minutes ago. Although we'd love to be able to announce a new Mac Pro, the iPhone 5, and an iPad 3, it appears that nothing has changed in the store, and the outage might have been due to a larger problem with the Interwebs.

Apple was not the only company getting hit with large issues today. VoIP carrier Ooma is reporting a nationwide outage although some California customers are reporting that things are beginning to get back to normal. John Gruber's Daring Fireball blog was down part of the morning, and readers and bloggers have been reporting that Twitter was visited by the Fail Whale, Facebook was temporarily faceless, and various ISPs are having issues.

We haven't heard what exactly is causing these issues and if they're related, but it seems odd that so many services would be experiencing issues at the same time. Keep an eye on TUAW and we'll update this post when we find out if what or who is causing the problems.
