Apple has taken its online store down this evening, and instead of just the usual "We'll be back" message, visitors are instead greeted with a rotating series of the message in 18 languages.
The tech giant doesn't seem to be in one of its traditional product release periods, so it's unknown why the store would be offline. We will update if something significant materializes.
In the meantime, checkout the gallery below of "We'll be back" messages and see how many languages you can identify.
Update at 5 a.m. PT July 18: The store is back up, at least in the United States, with no visibly significant change. The mystery deepens.
