Although it’s working for us, we’re getting reports from users that MobileMe email is down, with users unable to log into me.com and unable to send or receive messages by IMAP.
Although mail.me.com does not respond to pings, and many users are reporting issues, the MobileMe status page says everything’s working as it should.
Clearly Apple is making some rather radical backend changes this weekend. This is not the first service outage to occur over the last few days. On Friday night, thousands of owners of iOS devices found themselves unable to use their devices as Apple’s iTunes activation servers went down.
In addition, over the weekend, many iTunes customers had problems with “invalid address” error messages after Apple seemingly changed the way iTunes address verification works.
All of these instances point to Apple making some changes on their backend. Given the upcoming debut of Apple’s new cloud services, my guess is these hiccups are indicative of Cupertino doing the prep work to launch iCloud.
