Last night, Apple sent an email with the message in the picture above, announcing to its developers that on January 26 it will close the system iTunes Connect for a few hours. Apple has scheduled some maintenance work on the system, everything should return to normal in a few hours, but nothing will work during the work, so be careful not to schedule anything for the night from Saturday to Sunday.
iTunes Connect will undergo scheduled maintenance for approximately four hours starting at 8 pm (PT) on Saturday, January 26.
During this time, content delivery and iTunes Connect will not be available.
Regards,
The iTunes Store team
