Mary Anne's domain name is in the process of being renewed. In the mean time, mail to her will bounce, and you probably won't be able to reach her web page. Everything should be working again in a day or two at most.
You can send her mail at her alternate address, firstname.lastname@example.org. You can even read her journal if you cleverly use the alternate URL for it. But don't bookmark that; when things get back to normal, you should go back to using the mamohanraj.com email address and URLs.
You probably won't be able to reach her by phone today; she's on the road, and her cell phone currently lets other people hear her but doesn't let her hear other people.
Ain't technology wonderful?
(Hmm—perhaps the cell phone is attempting to demonstrate the SNAFU Principle by not allowing anyone to communicate with the King.)
