Massachusetts residents signing up for health plans endured hour-long waits over the phone ahead of Wednesday's midnight deadline.
But online, the state's website handled the last-minute load.
The revamped Health Connector website did not suffer the same outages and delays as last year. Thousands of people without insurance through their employers were able to sign up for health plans during the day. To ease the demand on the call center, Connector official Maydad Cohen extended the deadline to pay for those plans.
"Given the heavy interest in signing up for January 1 coverage, we will accept online and paper payments through Sunday, December 28," he said.
The Health Connector call center will be open on Sunday to help those who did enroll by yesterday's deadline, but still have to set up payment for their health insurance.
