WASHINGTON — The federal government's health care enrollment website — HealthCare.gov — went down briefly early Monday for extended maintenance as heavy traffic was building on the last day of open enrollment for 2014.
At one point, the site told visitors that it was "down for maintenance" and asked people to "please try again later." At other points, visitors were told there was heavy traffic on the system and were asked to remain online in a "virtual waiting room" until they could be connected.
Administration spokesman Aaron Albright said the website undergoes "regular nightly maintenance" during off-peak hours and that period was extended Monday because of a "technical problem."
He did not say what the problem was, but a statement from the Department of Health and Human Services called it "a software bug" unrelated to the volume of prospective applicants.
Albright said the website is typically down for maintenance during the period from 1 a.m. to 5 a.m. ET, and that as a result of the technical problems the site was down for at least three additional hours Monday morning. The site was largely restored by 8 a.m. ET.
The hiccup came as the Obama administration and its allies made a last-minute push to persuade Americans to enroll in health insurance under the Affordable Care Act.
Monday at midnight is the deadline for open enrollment and the last chance to avoid a penalty for not purchasing insurance in 2014, which people will pay with their federal income taxes next year.
Those who start the process — either by working on a paper application with a navigator, attempting to enroll online, or talking with a call center representative — may continue the process after the deadline passes.
Administration officials said interest was surging as the deadline neared. Sunday evening, Health and Human Services announced 2 million visits over the weekend to HealthCare.gov, the federal government's enrollment site.
In the last week alone, the call center handled a record 2.5 million calls, surpassing the 2.4 million it received during the entire month of February.
Over the weekend, HHS Secretary Kathleen Sebelius appeared at a Baptist church in Miami to urge Floridians to sign up before the deadline. She planned a fresh round of television interviews with local stations Monday to boost enrollment numbers.
An interview with Vice President Biden encouraging young people to enroll will air Monday on celebrity chef Rachael Ray's talk show.
"The traffic and energy and interest this weekend shows many more are interested in the coverage," White House spokeswoman Tara McGuinness said Sunday afternoon.
Republicans saw the situation differently.
In an op-ed appearing in Monday's editions of USA TODAY, Sen. Tom Coburn, R-Okla., said the vast majority of enrollees were previously insured. Getting Americans to "re-enroll in insurance is no great achievement," he said, "particularly when many of those customers were forced to give up plans they liked."
Sen. John Barrosso, R-Wyo., said the administration is "cooking the books" on enrollment figures. The real test "is what kind of insurance will those people actually have," he said during an appearance on Fox News Sunday.
President Obama announced Thursday that more than 6 million people had enrolled in the federal and state health exchanges, a goal projected by the Congressional Budget Office to ensure the system is sustainable.
Administration officials have not released updated numbers, but there were signs that enrollment numbers have grown since Thursday's milestone was announced.
State officials in New York said Friday that it had bumped up enrollment in private plans almost 25,000 from the previous week, and 70% of the enrollees had not had insurance before. California has already met its goal, but its executive director, Peter Lee, planned to visit several enrollment sites over the weekend. In Washington, D.C., gospel artist John Kee and songwriter Brittney Wright performed at a "gospel enrollment concert" Friday.
The government will have to wait for the insurers to release payment data, as well as information about the newly insured, to answer. However, some states, such as California, have reported payment rates as high as 85%.
White House officials Sunday released a memo that details the administration's public outreach to tout the law. One example: White House officials, Cabinet secretaries and "celebrity surrogates," including NBA standout Kobe Bryant and actress Kerry Washington, have held more than 300 radio interviews in the last six weeks, officials said.
