The managers of HealthCare.gov feared early on that adding capacity to solve traffic issues would highlight even more problems.
Officials at the Center for Consumer Information & Insurance Oversight, the U.S. Department of Health and Human Services agency directly responsible for overseeing the exchanges, talk about the problems in "CCIIO-Wide War Room Notes."
HealthCare.gov went live Oct. 1.
The House Oversight & Government Reform Committee posted the CCIIO HealthCare.gov war room notes on the Web late Thursday.
HHS officials have repeatedly declined to provide detailed federal exchange application or enrollment data, saying they have no confirmed, reliable information.
House Oversight officials note in a comment on the war room notes that, as of Oct. 3, HealthCare.gov users finished fewer than 250 enrollment transactions.
But the notes' authors focused more on listing problems and describing efforts to address them.
On the afternoon of Oct. 2, for example, consumer traffic remained high, the system crawled along, and managers reported as many as 40,000 in the "waiting room."
A mechanism allowing carriers to enroll consumers directly wasn't working either.
