FAIRBANKS- Many people using get stuck before they can start enrolling in the health exchange. The webpage says it’s the volume of people causing the slowdown.  Enrollment Specialists with Enroll Alaska say they’re facing the same hang-ups. Right now, the company has a backlog of about 500 customers that are interested in applying to the exchange and agents are scheduling follow-up appointments. The online marketplace went live Tuesday, and officials urged patience, noting open enrollment runs through March. Specialists hope the website will be working better by Monday, but nobody can say when the slowdown will be fixed.
