WASHINGTON — With a March 31 deadline to sign up for insurance under President Barack Obama’s health law approaching, more than a million people a day are visiting HealthCare.gov, administration officials said Wednesday.


The site — the main portal for insurance marketplaces in 36 states — got 1.2 million visitors Tuesday and 1.1 million visitors Monday, according to the administration.


At the same time, call centers received more than 500,000 calls over those two days.


Despite the crush, the website, which crashed repeatedly last year, has been stable, said Kurt DelBene, a former Microsoft executive who has been overseeing the website operations as a senior adviser to Health and Human Services Secretary Kathleen Sebelius.


"Since the traffic started to climb, we have seen only minor issues, all of which have been addressed rapidly," DelBene said.
