AUGUSTA, Maine (AP) – There may be some brief delays for anyone trying to sign up for coverage on Maine’s federally-run health care exchange as heavy traffic may slow down the website. Today marks the first day of enrollment on the exchange or marketplace, a key component of President Barack Obama’s Affordable Health Care Act. Consumers seeking information from the exchange received messages saying “please wait” for several minutes or the “system is down.” Joseph Ditre of Augusta-based Consumers for Affordable Health Care says the delays show the heavy interest in the exchange. He says consumers can sign up by phone or through organizations like a community health center and should remember they have until Dec. 15 to enroll and still be covered by Jan. 1.
