CGI Group Inc. is the company behind the Obamacare website. New month CGI's contract with the U.S. federal government expires, and they will be replaced by Dublin based Accenture Plc to complete any unfinished work on healthcare.gov and run the site. When the website first launched on Oct. 1 the site was plagued with delays, error messages and hang ups that stopped people from completing applications. Accenture, built California's better performing state system. Aaron Albright, a spokeman for the U.S. Centers for Medicare and Medicaid Services confirmed the decision in a email, "We are working with our contract partners to make a mutually agreed upon transition to ensure that healthcare.gov continues to operate smoothing for consumers."
