The U.S. Department of Health and Human Services, which administers the Patient Protection and Affordable Care Act (PPACA), announced at 9:25 a.m. that the new PPACA public exchanges are "open for business," in spite of budget battles that have led to a partial shutdown of the federal government.
HHS spokeswoman Erin Shields Britt said at midday Tuesday that more than 1 million people had visited the HHS PPACA exchange site, HealthCare.gov, in the past day.
"There were five times more users on the marketplace website this morning than have ever been on the Medicare.gov at one time," the spokeswoman said.
Early in the day, users were getting error messages and messages about the site being overloaded.
The spokeswoman said HHS expects the site to speed up in the coming hours.
