(CNNMoney) A malfunction in key technology behind the Obamacare website left users unable to apply for health coverage late Sunday.
Joanne Peters, a spokeswoman for the Department of Health and Human Services, said a vendor networking issue at Verizon subsidiary Terremark was to blame.
Peters said the vendor had “experienced a failure in a networking component,” and the attempted fix crashed the system.
Peters said that HHS chief Kathleen Sebelius had discussed the problem with Verizon CEO Lowell McAdam.
Verizon spokesman Jeff Nelson said his company was working on the issue and it would be “fixed as quickly as possible.”
