Des Moines Public Schools district was hit with a recent cyberattack.
The largest school district in Iowa Des Moines Public Schools was forced to cancel all their classes on Tuesday after taking all network systems offline due to unusual activity on their network. The announcement for the cancelation was published on Monday when the district added that athletics and activities were still scheduled to take place.
