Is anyone else having problems with Back to my Mac this weekend / today? System status says it was down for maintenance but is back up: Maintenance - 7/31/2009, 22:45 - 8/1/2009, 12:30 PT Due to scheduled maintenance, some MobileMe members may have been unable to use Back to My Mac on Mac OS X Leopard computers. Normal service has been restored. We apologize for any inconvenience. Down again?
