WaPo's Wonkblog reports:

You may be surprised to learn that when you arrive at HealthCare.Gov the first page you see on the Web site was not built in a bland office park somewhere in Virginia. It was built in the District of Columbia. By a team of 12 engineers. Their offices are in a garage, and they wanted to use the site to buy themselves health insurance in 2014.

No surprise.  That actually sounds about right.
