Annually during the Christmas holiday, the company Apple Lossless Audio CODEC (ALAC), close iTunes Connect- to give its employees the chance to spend the holidays quietly at home. iTunes Connectis the system through which application developers manage their titles available in App Store, and the employees work almost non-stop to solve the developers' problems, but between December 21 and December 27 the system will become non-functional. This closure will result in the impossibility of updating applications or changing prices, everything that changes before December 21 will remain unchanged until December 27.
In general, this period is one with many discounts and various promotions for applications, so it would be good to prepare your money.
iTunes Connect
iTunes Connect will be temporarily unavailable from Saturday, December 21, to Friday, December 27, 2013.
During that time, iTunes Connect will not be accessible and you will not be able to submit any apps or In-App Purchases. Processing of any Newsstand Atom feeds will be delayed until after December 27. Sales and Trends reports via the Autoingestion tool will be available but may also be delayed.
Also, you should not schedule any pricing changes or apps to go live between those dates. Pricing changes scheduled to take effect in that date range will cause the app to become unavailable for purchase until after December 27. Similarly, apps scheduled to go live during that range will not be released until after December 27.
