9to5Mac reported a message they received from Apple as a notification that today there will be a schedule maintenance of iTunes Connect and that Apple online stores such as iTunes and the Mac App Store will be unavailable. Recently there was a maintenance just like the one scheduled for today that people rumor to be a test simulating possible downtime because of the rush to buy Lion upon release.
According to the message the maintenance is scheduled for 9 AM to 4 PM PDT and will affect digital stores in Mexico, the United Kingdom, Australia, Switzerland, Japan, or Norway and changes made by a developer in this time are not recommended.
Lion is coming even closer with rumors of new Macs mid-July that I strongly believe especially those tipped to 9to5Mac by their famous Mr. X that fails to be incorrect. Lion should be release alongside or a few days before said new Macintosh computers that will come with Mac OS X Lion pre-installed.
A 'close to Apple' SpeakApple source also says that the United Kingdom should be seeing Lion around 1 AM (UK time). If this is true then the United States should be seeing it a short time before the UK or at the same time.
The great thing about the Mac App Store distributing Lion is that people around the globe can easily get it at the same time if Apple allows because they have many servers that different countries can be distributed among making the load lighter and giving the world Mac OS X Lion without having to ship disk copies around the globe.
The whole message says:
Dear BLANK,[via 9to5Mac, SpeakApple]
iTunes Connect will be undergoing scheduled maintenance on Wednesday, July 13 from 9 a.m. to 4 p.m. PDT.
During this time, iTunes Connect will still be available. However, pricing changes made between 9 a.m. and 4 p.m. PDT will cause the app to become unavailable for purchase until maintenance is complete, at which point the app will become available at the new price. To avoid interruptions to the availability of your apps, do not make price changes during this time.
Lastly, customers may not be able to purchase apps in the Mexico, U.K., Australia, Switzerland, Japan or Norway storefronts during the scheduled maintenance.
