Looking at Whois, the expiration date was October 8th. How could no one at the American Heart Association know that their website was down for over a week? You would think they would have taken a hint when the donation phones stopped ringing.
The sad thing is they could have paid for a registration 10 years out for a few hundred dollars. Instead, they probably lost hundreds of thousands of dollars in donations, while the website was down over the last week.
