HealthCare.gov experienced an outage early Monday morning, The Hill's Healthwatch reported. As the midnight enrollment deadline approaches, visitors to the website discovered the tabs to begin the overall process did not work. "The system isn't available at the moment," was the message displayed on a number of webpages early this morning. After numerous problems last fall, the Obama administration made it a priority to improve the site. An official told Healthwatch late-night tech work that extended into Monday morning caused the error. Meanwhile, roughly 2 million people visited HealthCare.gov this past weekend. Article
