Clock’s ticking. Healthcare.gov is unlikely to have fixed all its glitches by the White House’s deadline at the end of November, a government official said Wednesday. The website, where Americans can sign up for health-care coverage under the Affordable Care Act, has not been able to hold up to the 20,000-30,000 Americans using it—half of its intended capacity. What’s more, CGI Federal, the contractor who built the site, has only fixed roughly 60 percent of the problems it has identified so far. President Obama and other White House officials have insisted the site will be running in tip-top shape by Nov. 30, but government officials and other contractors working on the site have concluded that the only way to fix the problems is for people to use other methods to sign up for insurance.
