Still down are Xcode automatic configuration as well as access to license agreements, Technical Support Incidents, program enrollments, and renewals in Member Center.
The company notes that if membership were set to expire during the downtime, it has been automatically extended and no App Store sales have been affected.
Apple Developer Update: Aug 5, 2013Apple's new Developer Center System Status page should be updated as the remaining services come back online.
We sincerely appreciate your patience as we work to bring our developer program services back online, and we want to give you an update on our progress. The majority of our developer services are currently online, including Certificates, Identifiers & Profiles, Dev Centers, software downloads, Videos, Apple Developer Forums, iTunes Connect, Bug Reporter, App Store Resource Center, and access to pre-release documentation.
We plan to reinstate most of the remaining services this week: Xcode automatic configuration as well as access to license agreements, TSIs, program enrollments, and renewals in Member Center. You can check the availability of these systems on our status page.
As a reminder, if your membership was set to expire during this downtime, it has been extended and your apps will remain on the App Store and Mac App Store.
We apologize for the significant inconvenience that our downtime has caused and encourage you to reach out to our support team if you need any assistance.
