Bad news for developers. Apple took down its developer portal due to an intrusion that it’s investigating. It’s also updating its systems to plug any potential holes. This is going to take some time.
Also bad is that developers can’t access new builds of iOS 7 and OS X Mavericks, which have released every two weeks on Mondays since they debuted. As website CultofMac has noted, this means that we probably won’t see the new builds, unless Apple can get things going before the end of the day. Regardless, it’s going to delay things a bit, it seems.
