Apple Deploys Developer Center System Status Page
It has been over a week since the Apple Developer Center Web site went offline, with no indication of when it will be fully back. However, Apple has created a status page displaying an itemized checklist of what services are online. (Alas, you can’t click the icons to bring services up and down!) In email to developers, Apple announced that it is prioritizing the order in which updated systems will be made available. Certificates, Identifiers & Profiles, Apple Developer Forums, Bug Reporter, pre-release developer libraries, and videos will be available first, followed by software downloads and remaining systems. (Most Developer Center systems have since come back online.)
Not really functioning if you want to join what appears to be now a three tier Developer system! e.g.,
Mountain Lion etc.
