On Sunday, the Department of Health and Human Services said in a blog post it was bringing in a "tech surge" of people from inside and outside government to help iron out glitches in the online insurance exchanges that are a central part of Obamacare.
The post noted that more than 20 million unique visitors to date have visited the site. So far, about 476,000 health insuranceapplications have been filed, said Obama administration officials.
On Sunday, the website was updated to provide additional information about other ways to purchase insurance through the exchanges, including by phone, in person or making in an application, Obama noted.
"While the website will ultimately be the easiest way to purchase insurance though the marketplace, it isn't the only way," he said.
He added that more staff have also joined the exchanges' call centers, which have been reached by calling 1 (800) 318-2596.
