Developers are experiencing severe problems using iTunes Connect, scattered reports say. The service is the conduit through which apps are submitted to the App Store, and during this week it has allegedly been stalling during uploads. The problem is said to be independent of browser or operating system choices, and to typically involve hangs midway through an upload, though some developers complain they cannot even begin the process.

One developer, Andreas Fink, says he has been unable to upload an app update for three days. Twitter discussion reveals that the upload failures are also widespread, at least affecting people in Europe as well as North America. Apple is believed to be aware of the service interruptions, but it has not offered an official explanation for them nor a timetable for having them resolved.
