It's still possible to think you've signed up and not get coverage.
Robert Zuehlke tried to sign up using HealthCare.gov on Monday.
It didn't crash or freeze, but there was this note that the site still can't handle a surge of users.
The White House says today 375,000 logged on between midnight and noon.
"We want to make sure that their experience is vastly improved," said White House Press Secretary Jay Carney.
Still, starting January 1st Americans who think they've bought coverage could get a surprise.
HealthCare.gov is still sending out some unusable sign-up files to insurance companies.
"If health plans do not receive complete and accurate enrollment files, then consumers may not be enrolled and therefore their coverage would not begin on January 1st," warns Robert Zirkelbach of America's Health Insurance Plans.
With the clock ticking until that January 1st deadline there is less than a month now to get the system right.
