FORT LAUDERDALE, Fla. (AP) — Consumers are reporting a mix of successes and failures as they try logging onto the updated site.

Brokers and online assisters in Utah say three of every four people who want to sign up for coverage on the federal government's online exchange are succeeding within an hour of logging in. Navigators in Wisconsin, Illinois, Alabama and North Dakota reported vast improvement, while staffers in South Florida and Iowa were stymied by glitches on the federal website, which is serving 36 states.

About 750,000 had visited the site by Monday night — about double the traffic for a typical Monday. By 10 a.m., with about 30,000 visitors and growing error messages and response times, federal health officials deployed a new queue system.
