ObamaCare website suffers new outage as Republicans say glitches only 'tip of the iceberg' The federal government's online portal to buy health insurance suffered another glitch Sunday when the data services hub, a conduit for verifying the personal information of people applying for benefits under the law, went down in a failure that was blamed on an outside contractor. "Today, Terremark had a network failure that is impacting a number of their clients, including healthcare.gov," HHS spokeswoman Joanne Peters said in a statement Sunday evening. [Health and Human Services] Secretary [Kathleen] Sebelius spoke with the CEO of Verizon this afternoon to discuss the situation and they committed to fixing the problem as soon as possible. Jeffrey Nelson, a spokesman for Verizon Enterprise Solutions, of which Terremark is a part, told the Associated Press: "Our engineers have been working with HHS and other technology companies to identify and address the root cause of the issue. It will be fixed as quickly as possible. The latest glitch came just days before Sebelius is scheduled to testify before the House Energy and Commerce Committee about the problems that have plagued the online health exchanges since they launched Oct. 1. "The incompetence in building this website is staggering," Rep. Marsha Blackburn, R-Tenn., the second-ranking Republican on the panel, told "Fox News Sunday." Republican lawmakers also signaled Sunday that their efforts to dismantle ObamaCare will go well beyond criticizing the problem-filled website, saying computer glitches are only the "tip of the iceberg" for the federal health care plan. Among the concerns of Barrasso and others are the millions of taxpayer dollars being spent on a slow, crash-prone website and Americans having to pay a tax penalty in March after trying, but failing, to sign up for insurance, while the president has exempted businesses from having to pay. Critics also argue some Americans will be forced to drop existing policies for more expensive, ObamaCare-approved ones, despite the president vowing that people could keep the insurance they liked and had.
