NEW YORK — Heavy volume contributed to technical problems and delays that plagued the rollout Tuesday of the online insurance markets at the heart of President Obama’s health care law, according to state and federal officials, who were watching closely for clues to how well the system will work and how many people will take advantage of it.
Many people who tried to compare plans and shop for coverage at healthcare.gov, the federally run exchange that serves as the marketplace for residents of most states, met with messages citing high traffic and advising, “Please wait here until we send you to the login page,” or “The system is down at the moment.” A state-run exchange in Maryland also posted a message saying it was “experiencing connectivity issues” and asking visitors to try again later.
Speaking at the White House, Obama said that more than 1 million people had visited the federal site by 7 a.m., more than five times as much traffic as experienced by Medicare’s website. He said his administration would fix technical problems and adjust to “this demand that exceeds anything that we had expected.”
States that operate their own enrollment sites reported widely varying levels of traffic, but most said the systems were working, though with some problems caused by having more people than expected go to the exchanges.
In the first few hours that their exchanges were operating, New York state’s reported 2 million visits, Kentucky’s 24,000, Illinois’ more than 62,000, and Connecticut’s 14,000. Most of those people were browsing and comparing options; the numbers attempting to enroll in an insurance plan were far smaller, and there were more problems reported with that process.
The administration has stressed that consumers could also phone call centers or go in person to social service agencies, which can be found at localhelp.healthcare.gov, that have been designated as “navigators” to help people through the process. But those systems also stumbled out of the gate, dependent on the same computer systems used by people who went online.
It was unclear to what degree problems with the federal websites were due to the kind of technical hurdles that supporters of the program had warned about and that opponents had predicted would demonstrate its unwieldiness. Federal officials conceded Tuesday that even if volume were low, computer problems would be making it hard for people to shop, compare prices, and enroll.
Some cybersecurity efforts raised the possibility that the system had been hit by a “denial of service” attack, in which people use linked networks of computers to cause a system to crash by flooding it with traffic.
Tuesday also brought a partial shutdown of the federal government, after the Republican majority in the House said it would pass a bill financing continued operation of the government only if that bill also eliminated money for the Affordable Care Act, known as Obamacare, or delayed its being put into effect for a year. The House has voted more than 40 times to undo all or part of the law, which was passed in 2010.
But the shutdown did idle some federal employees who had been promoting the expansion of coverage. A White House spokeswoman, contacted about snags in the rollout, said, “Due to the lapse in appropriations, I am not in the office and am not available to answer your message.”
Insurance bought through the exchanges by Dec. 15 would take effect Jan. 1. The open enrollment period runs through March. The 2010 health care law calls for most Americans to have insurance. Those who go without coverage may be subject to tax penalties.
In a point repeated by officials around the country, Governor Pat Quinn of Illinois, a Democrat who supports the program, said that given the timetable, it would be a mistake to expect a lot to happen on the first day. “What we want folks to do is get educated, and then get enrolled,” he said.
Despite months of feverish preparation, officials began the day unsure whether the exchanges had overcome a range of problems, including with Spanish-language versions, subsidy calculators, and programs to enroll small businesses.
Nor can officials do more than guess how many people actually will buy private coverage through the exchanges.
The stakes are immense for Obama, whose signature achievement is the 2010 law that is supposed to push the United States closer to universal health care. Defending the law in the 2012 campaign, he defeated a Republican opponent, Mitt Romney, who vowed to repeal it.
A trouble-plagued launching, accompanied by the complaints of frustrated consumers, could undermine political support for the law, while tepid participation by the uninsured could weaken its financial underpinnings, which depend on the largest possible number of people paying into the system.
