Apple today notified developers of scheduled maintenance via e-mail.
This coincides with reports that Lion will be launching this Thursday along with updated Macs. iTunes Connect is where developers upload their content to made available on the App Store. Lion will be available exclusively on the Mac App Store.
The e-mail follows:
iTunes Connect will be undergoing scheduled maintenance on Wednesday, July 13 from 9 a.m. to 4 p.m. PDT.
During this time, iTunes Connect will still be available. However, pricing changes made between 9 a.m. and 4 p.m. PDT will cause the app to become unavailable for purchase until maintenance is complete, at which point the app will become available at the new price. To avoid interruptions to the availability of your apps, do not make price changes during this time.
Lastly, customers may not be able to purchase apps in the Mexico, U.K., Australia, Switzerland, Japan or Norway storefronts during the scheduled maintenance.
