As of my writing (on Thursday, July 25), Apple’s developer portal has been offline for days. As you can see on the dashboard, just about everything is down. If you go to a dev center, you see this message:
We apologize for the significant inconvenience caused by our developer website downtime. We’ve been working around the clock to overhaul our developer systems, update our server software, and rebuild our entire database. While we complete the work to bring our systems back online, we want to share the latest with you. We plan to roll out our updated systems, starting with Certificates, Identifiers & Profiles, Apple Developer Forums, Bug Reporter, pre-release developer libraries, and videos first. Next, we will restore software downloads, so that the latest betas of iOS 7, Xcode 5, and OS X Mavericks will once again be available to program members. We’ll then bring the remaining systems online. To keep you up to date on our progress, we’ve created a status page to display the availability of our systems.
As you may have read elsewhere, the reason for the outage is apparently a researcher found a massive security hole in the App dev center system. To prevent the flaw from being exploited, Apple took the entire system down – on July 18. That’s right, it’s been over a week.
