obamacare website screenshot*(Via NBC News) – The federal government shut down on Tuesday, but Obamacare was full steam ahead … sort of.

The new HealthCare.Gov website collapsed early Tuesday morning under the weight of 2.8 million users,said Marilyn Tavenner, administrator of the Center for Medicare and Medicaid Services.

“As with any product launch, there will be glitches. We will fix them,” Tavenner told reporters on a conference call.

“Sorry, Health Insurance Marketplace Live Chat isn’t available right now,” the website advised. “We apologize for the inconvenience. Please try again later, or call your Customer Service Center at 1-800-318-2596.”

President Barack Obama said it crashed under the weight of a flood of users. ““More than 1 million people visited healthcare.gov before 7 in the morning,” he said, adding:

“There were five times more users than have ever been on medicare.gov at one time. That gives you a sense of how important this is to Americans around the country,” Obama said in an address aimed mostly at criticizing the federal government shutdown.
