The White House says that 20 percent of Americans will not be able to purchase health insurance on Healthcare.gov, the new online health insurance exchange marketplace. 

Although the Obama administration is working to fix the botched site by Nov. 30, White House press secretary Jay Carney said that 1 in 5 who start the process online will not be able to purchase insurance, The Associated Press confirms. 

Carney said that 20 percent will not be able to purchase insurance due to technical problems. He also said that some will not be comfortable with using a computer to purchase insurance, and others have a tax situation that is too complicated for the website to determine eligibility for subsidies. Carney said that call centers can serve those individuals better. 

He added that the Obama administration is considering other ways to get people enrolled in the exchange, such as through direct sign-ups through insurance companies. 

While 20 percent will not be able to purchase online insurance, the White House is confident that the other 80 percent will be able to successfully enroll in an insurance plan by the Nov. 30 deadline, according to CNN. 

"We are measuring progress by key metrics including error rate - once as high as 6 percent -now less than 1 percent but needs to be lower; and response time - which was eight seconds several weeks ago and is now less than one second -still working to get it faster," a senior administration source told CNN.

However, an industry source warned that the 80 percent figure was "not well defined."

"The 80 percent figure has been discussed in the war room, but the figure is not well defined. It sounds more like a benchmark for the policy than the technical capability of the site," the source said. "A technical benchmark would measure whether people can buy health care plans online and the related metrics involved in the transaction (page load times, error rates, etc.)."

Another source said that some issues may force some of the remaining 80 percent to finish enrolling offline. 

"But they would still be able to have a positive website experience," the source added.

Technical teams are working around the clock in McLean, Va. to try to fix the glitchy site. Every day, tech experts discuss problems form the website during a call in the morning and one in the evening. The so-called "war room calls" are led from a HealthCare.gov site in Herdnon, Va., a Washington suburb.
