iTunes Match Temporarily Overwhelmed by Huge Demand

iTunes Match is finally here, although it looks like your months-long wait might be extended a bit. Turns out that due to excessive demand, Apple is temporarily blocking new registrations.

When we tried to sign up for iTunes Match we were prompted with the error above, informing us that new iTunes Match subscriptions are temporarily unavailable due to excessive demand, and that we should please try again in an hour. Blast! We'll keep trying, but in the mean time would you all please stop? We're dying to get in! [iTunes]
