As reported in early October, Apple is shutting down the .Mac HomePage service today. The .Mac HomePage service was a feature that allowed users to publish webpages using their .mac account. The feature was first discontinued in July 2009 (users were unable to create new content); today Apple is pulling the plug on the service by disabling viewing of already-published content.
The files won't be permanently deleted, though. As Apple explains in a support document:
Can friends and family still view my published pages?
After November 8, 2010, all photos, movies, and files shared using .Mac HomePage will be unavailable for viewing on the web. Web Pages published using iWeb or Aperture will not be affected.
Will my content be deleted after November 8, 2010?
No. All of your content is still on your iDisk and can be accessed by going to me.com/idisk and clicking Home in the sidebar. The HTML files that make up your site can be found in the Sites folder, and any pictures or movies you have used for your pages can be found in the Pictures and Movies folders respectively. You must remain an active MobileMe member to access your iDisk.
Apple's current sync and web publishing solution, MobileMe, retails at $99 per year and comes with a 60-day free trial. We highly recommend it as a way to sync information across devices (bookmarks, settings, email accounts, calendar), although we're huge fans of Dropbox when it comes to file storage.
