Apple's online marketplace has officially gone down for a brief hiatus.

The company on Tuesday posted an alert on its Apple Store saying -- in a cycle of messages in multiple languages -- that its marketplace will be down while it's being updated. The move comes just hours before Apple plans to hold a special event, starting at 10 a.m. PT, at which it's expected to unveil two new iPhones -- the iPhone 5S and iPhone 5C. CNET will be there to bring you all the details in the moment.

Rumors have been swirling for months over what Apple might and might not unveil at today's event, but so far, the company has remained tight-lipped on its plans. That the Apple Store has gone down is a sure sign that something is coming today, but as Apple has previously done with other major events, its store takedown is by no means an indication of what it has planned.
