Is Scheduled for Maintenance During Obamacare Enrollment?

News reports correctly describe the facts surrounding scheduled "Obamacare" web site downtime during November and December 2017.

  • Published 25 September 2017


The Department of Health and Human Services has scheduled web site maintenance for on most Sundays during Obamacare open enrollment.


In September 2017, numerous news accounts reported that the web site was scheduled to be shut down for maintenance on several occasions during the 2018 “Obamacare” health insurance open enrollment period, which runs from 1 November to 15 December 2017, prompting queries to us from readers about the issue.

Kaiser Health News, a self-described “nonprofit news service committed to in-depth coverage of health care policy and politics,” reported that:

The Trump administration plans to shut down the federal health insurance exchange for 12 hours during all but one Sunday in the upcoming open enrollment season. The shutdown will occur from 12 a.m. to 12 p.m. ET on every Sunday except Dec. 10.

The Department of Health and Human Services will also shut down the federal exchange — — overnight on the first day of open enrollment, Nov. 1. More than three dozen states use that exchange for their marketplaces. HHS officials disclosed this information during a webinar with community groups that help people enroll.

Kaiser Health News reporter Phil Galewitz tweeted what appeared to be a slide from a related presentation, including details of the scheduled maintenance:

The same slide was independently tweeted by Vox‘s Sarah Kliff:

A spokesperson for the Center for Medicare and Medicaid Services (CMS), which runs, confirmed the maintenance schedules reported by Kaiser Health News and Sarah Kliff:

Maintenance outages are regularly scheduled on every year during open enrollment. This year is no different. The maintenance schedule was provided in advance this year in order to accommodate requests from certified application assisters. System downtime is planned for the lowest-traffic time periods on including Sunday mornings.

That spokesperson also said the periods set out for web site maintenance constituted the maximum anticipated amount of downtime, and averred that the actual amount of downtime might end up being less. (We asked CMS to clarify the times involved in the 1 November downtime, which the presentation slide only describes as “overnight,” but we did not receive a response in time for publication.)

The Trump administration has already cut in half the Obamacare open enrollment period, truncating the original period of 1 November 2016 to 31 January 2017 (three months) to the shorter period of 1 November to 15 December 2017 (six weeks).

As pointed out by Kaiser Health News, this year’s web site maintenance schedule means that will be online for 93% of the total time during the six-week open enrollment period. (If we assume the “overnight” downtime on 1 November will last 12 hours, then the web site will be online for 1,008 out of 1,080 hours.)

According to the United States Digital Service, which is part of the Executive Office of the President, the web site was online 99.9% of the time during the 2015 and 2016 open enrollment periods, which were themselves twice as long as the upcoming open enrollment period.
