Analysis: IT Experts Question Architecture Of Obamacare Website

Days after the launch of the federal government's Obamacare website, millions of Americans looking for information on new health insurance plans were still locked out of the system even though its designers scrambled to add capacity.

Government officials blame the persistent glitches on an overwhelming crush of users - 8.6 million unique visitors by Friday - trying to visit the HealthCare.gov website this week.

The U.S. Department of Health and Human Services, which oversaw development of the site, declined to make any of its IT experts available for interviews. CGI Group Inc, the Canadian contractor that built HealthCare.gov, is "declining to comment at this time," said spokeswoman Linda Odorisio.

Five outside technology experts interviewed by Reuters, however, say they believe flaws in system architecture, not traffic alone, contributed to the problems.
