Apple has just informed developers that all of their developer services are now online. Some of Apple’s services have been down for over 3 weeks, making it impossible for developers to launch new iOS apps, log in to the member center, use iTunes Connect and more Apple services. In an email send to developers, Apple is giving all developers an extension to their developer memberships by one month to account for the downtime.

We are pleased to let you know that all our developer program services are now online. Your patience during this time was sincerely appreciated.

We understand that the downtime was significant and apologize for any issues it may have caused in your app development. To help offset this disruption, we are extending the membership of all developer teams by one month. If you need any further assistance, please contact us.

Apple’s Developer Center went offline on July 18th because the developer website had been hacked and some developer information may have been leaked.
