The Obamacare website, Healthcare.gov, was down this morning in the final hours before open enrollment for online federal health exchanges ends. If you tried to log on to Healthcare.gov,  you couldn’t. And new users couldn’t create an account. Here’s how it looked:

After more than six months in operation and over $600 million to make the thing, Healthcare.com still stinks on ice.

Today’s crash was just sad irony:

It’s only fitting that http://t.co/sNezRWaXdB not work on the last day of #enrollment, as it didn’t work on the first day of enrollment.

Meanwhile, as Healthcare.gov was down, the White House’s federal exchange doomsday clock was showing the wrong day, hour, minute, and second:

CNBC confirmed the site’s failure:

he federal government’s Healthcare.gov health insurance website’s application and enrollment system went down on the final day to begin the process to apply for health insurance for 2014.

Monday is the deadline to sign up for private health insurance in the new online markets created by President Barack Obama’s health care law. So far, about four out of every five people enrolling have qualified for tax credits to reduce the cost of their premiums.

According to a statement from the U.S. Department of Health and Human Services: “HealthCare.gov marketplace application and enrollment system is currently unavailable. The tech team is working now to bring the system online as soon as possible.”

The online application has been unavailable since 3:20 a.m.
