CNN - Happening now: The Obamacare hearing
10:34 a.m. ET - Rep. Anna Eshoo, D-California, represents Silicon Valley and says she's surprised that the witnesses don't seem to find the technical issues as problematic as users have.
"This is the 21st century. It's 2013. There are thousands of websites that handle concurrent volumes far larger than what healthcare.gov was faced with. You keep speaking about unexpected volumes, Mrs. Campbell...I think that's really kind of a lame excuse. Amazon and eBay don't crash the week before Christmas," she says.
Eshoo asks if there was testing done. Campbell says they had independent contractors do CGI's testing, and their systems worked.
