The website to enroll in health insurance through ObamaCare was scheduled to go offline for 12 hours starting Saturday night for maintenance.
The Department of Health and Human Services said it would make updates to the online application and enrollment tools.
"The HealthCare.gov tech team is performing extended maintenance this weekend to improve network infrastructure and make enhancements to the online application and enrollment tools,” HHS spokesperson Joanne Peters said in a statement.
The particular type of maintenance has occurred twice before since the HealthCare.gov went online last month, the department said.
The website experienced outages earlier this week while Secretary Kathleen Sebelius gave testimony before Congress. It appeared to be the same kind of outage that occurred last weekend, which the Centers for Medicare and Medicaid Services attributed to Verizon Terremark.
The company will be working on the website’s infrastructure Saturday.
The administration expects the website to be functioning normally by the end of the month.
HHS announced earlier this week that employees from Oracle and Google would be working on the tech surge to fix the website which the administration announced late last month.
The rollout of the website, the main hub to access the online marketplace, has experienced technical difficulties since its launch. House Republicans released internal notes earlier this week showing less than 300 people had successfully enrolled three days into the launch.
HHS has continuously said it will not release enrollment statistics until later this month.
