10. Booz Allen of Carlyle Group and Edward Snowden Fame is handling some of this?

From your Post:
A test of the site this morning had me waiting four minutes to get to the signup page; others got on instantly. But problems persist beyond the front door. The contractors responsible for the exchange—CGI Federal for the website itself, Quality Software Systems Inc. (QSSI) for the information "hub" that determines eligibility for programs and provides the data on qualified insurance plans, and Booz Allen for enrollment and eligibility technical support—are scrambling to deploy more fixes. Technical support call center operators continue to handle an onslaught of calls from users who can't get back into the system after registering.

WIKIPEDIA:

As of August 2008, Booz Allen Hamilton’s former parent company (which used the Booz Allen name itself) divided in two. The Booz Allen Hamilton moniker was retained by the half focusing on U.S. governmental matters, with Booz & Company taking sole control of its commercial strategy and international portfolio. Booz Allen Hamilton is majority owned by private equity firm The Carlyle Group, while Booz & Company is owned and operated as a partnership.[12] On November 17, 2010, Booz Allen's shares of common stock began trading at the New York Stock Exchange.

In June 2013 when Booz Allen employee Edward Snowden made the 2013 mass surveillance disclosures including Booz Allen's support in developing the NSA's classified mass surveillance and data collection program PRISM, Booz Allen condemned Snowden's actions as "shocking" and "a grave violation of the code of conduct and core values of our firm" and fired him.[13] The United States Air Force issued a statement that Booz Allen did nothing wrong and may continue its business with the government.[14]
