After the hack last week the Apple Developer site is still offline - it's been now 6 days. As the beta 1 of iOS 7 expired yesterday this might have hurt some people who did not have a beta2 or 3 downloaded (like me).
For now Apple put up a status page to show which services are available.
So far only iTunes Connect and the Bug Reporter Service are back online. Whatever Apple does, it needs to speed up the process a little bit.
