Health care website is operating smoother

WASHINGTON – As the Obama administration’s weekend deadline for a smoothly functioning online marketplace for health insurance arrives, more than a month of frantic repair work is paying off with fewer crashes and error messages and speedier loading of pages, according to government officials, groups that help people enroll and experts involved in the project.

But specialists said weeks of work lie ahead if the $630 million site,, is to accommodate the expected flood of people seeking to buy health insurance, including a major reconfiguration of much of the computer hardware. Without the additional changes, experts predict, the website may continue to crash during periods of peak usage.

Beyond the prospect of potential delays for consumers, insurers warn that problems remain in the invisible “back end” that transmits enrollment information to them. That data has been plagued by inaccuracies, insurers say. Administration officials have been unwilling to disclose the error rate.

As late as Wednesday, the site still continued to slow down when 30,000 users tried to log on simultaneously, according to project specialists. A batch of hardware upgrades and software fixes scheduled for this weekend, administration officials say, will allow the site to handle 50,000 simultaneous users, as promised, by Dec. 1, which is Sunday.

The Health and Human Services Department announced that the site would be shut down for 11 hours Friday night in order to put those upgrades into place, on top of the usual four-hour timeout for maintenance Saturday night.

Although the administration has postponed a December marketing campaign, fearful that the site would collapse under a surge in traffic, five weeks of repair work have clearly made the exchange better. From last Sunday to Tuesday, nearly 20,000 users managed to enroll in insurance plans, the most for a three-day period, according to people familiar with the project. By comparison, fewer than 27,000 users picked an insurance plan on the federal site in the entire month of October.

And pages that once took an average of eight seconds to load now show up in a fraction of a second. The rate at which a user sees an error message has dropped from about 6 percent to 0.75 percent.

But the pace of enrollment must pick up drastically if the administration is to meet its target of signing up 7 million people by the end of March, the number that insurers say they need to spread risks and keep prices down. While some states that built their own sites are making better progress enrolling people, applicants in 36 states, with two-thirds of the nation’s population, depend on the federal site. The problems with the federal website shouldn’t affect New Yorkers who can enroll in plans using the much-better functioning state marketplace available at

At this week’s rate of enrollment, those enrolled through the federal exchange would total fewer than 1.1 million by the March deadline. Few insurance executives expect alternative options for enrolling, including by phone, mail or in person at counseling centers, to make up that gap.

The Obama administration has already spent more than $9 million beefing up the federal website’s computing power with additional servers and other hardware. The reconfiguration of the data center – the website’s computer brain – is expected to cost millions more and require up to another month of work, specialists said.

Experts involved in the repair work say the overhaul is necessary because bursts of traffic beyond the designed capacity could bog down the site, forcing users into an electronic queue until emails notify them that they can return.

The only solution, several experts said, is to reconfigure many of the site’s computer servers so that they are dedicated solely to’s tasks.

Currently, most of the servers juggle demands from other clients as well.

One expert said the site needs to be able to handle 100,000 simultaneous users to provide a safe margin of error.

“Think of it as Version Two,” he said.

Tests conducted this week for the New York Times by a California-based company that evaluates websites for major commercial clients found that the site remains too complicated for many users and is still prone to errors and delays.

“There are too many obstacles and unexpected hurdles people have to jump to sign up,” said Jonathan Hicken, research director at User Testing, the Mountain View, Calif.-based company that conducted the tests.

Consumers interviewed by the New York Times this week reported varying degrees of success. Aimee Berner, 59, of Glenview, Ill., said she was still not able to finish the application that she began weeks ago. “At least for me, the glitches are still there.”

But on Friday, Dan Wilson, 28, of Madison, Wis., said he had better luck.

“I needed to make a decision about whether I was going to keep my current plan or find a new one. I was successfully able to get through and get the information I needed,” he said.

In early October, he said, he found the site “just useless.”
