WASHINGTON (AP) — Outages affecting the Obama administration’s balky health insurance website slowed much needed fixes this week, but officials said Friday they remain on track to have HealthCare.gov humming along by the end of the month.

The government says the website went down for extended periods due to a hardware failure at a support facility owned by Verizon. The federal site wasn’t working during congressional testimony by Health and Human Services Secretary Kathleen Sebelius this week, creating an embarrassing juxtaposition.
