Obama administration officials on Wednesday said an improved HealthCare.gov website should be able to break its own record for online traffic next month, when consumers begin using the site to enroll in private health insurance for 2015. Andrew Slavitt, a top U.S. official working to implement the law known as Obamacare, said the goal for traffic capacity is "significantly more than on the highest peak day." That peak day was March 31, the last official day for 2014 enrollments, when the site handled more than 125,000 users at a time, for a total daily volume of 4.8 million visitors.
