White House press secretary Jay Carney on Wednesday said he was “confident” that the healthcare.gov website registering consumers in Obamacare will be fixed before the administration’s Nov. 30 deadline, but cautioned that further improvements could be made after that date.

“We make assessments all the time and we are confident we are on track to achieve that,” Carney told reporters. “If that changes, we will certainly let you know.”

Carney added that even at the end of November, the administration would still weigh ways to continue to improve the troubled website.

“It's not just a goal that we'll all evaluate on Nov. 30," he said.

After the botched rollout of the website on Oct. 1, the administration tapped former Office of Management and Budget Director Jeffrey Zients to oversee a “tech surge” to repair the website. Zients vowed to have the website working “smoothly” for most users before December.

But a report in the Washington Post on Wednesday said that top officials are concerned that they may not be able to have the website’s many technical glitches fixed before the end of November as promised. The report said that the website is still unable to handle the expected visitor traffic.

“There are still problems that need to be addressed even as the tech team works through a punch list of issues that need to be resolved,” Carney conceded on Wednesday.

“We are not where we will be and where we want to be on Nov. 30,” he added “But it remains the case that we believe the website will be working smoothly for the vast majority of users by the end of the month.”

Carney said that there had been “measurable progress” and that error rates for users had dropped below 1 percent.
