Computer glitches cause widespread disruption for online classes across the U.S.

Students across the U.S. ran into computer glitches Tuesday as they began the school year with online instruction at home because of the coronavirus.

The online learning platform Blackboard, which provides technology for 70 of the nation’s 100 biggest districts and serves more than 20 million U.S. students from kindergarten through 12th grade, reported that websites were failing to load or were loading slowly, and users were unable to register on the first day of school.
