A ransomware attack forced an early dismissal at Nantucket Public Schools on Tuesday and canceled classes on Wednesday, according to the administration.
In a notice sent to the families Tuesday, Superintendent Elizabeth Hallet said they had to shut down the internet and all student and staff devices after the attack.
The IT department continued to assess the damage Wednesday. It was not immediately clear what, if any, information may have been compromised by the attack.
Athletic practices and the Nantucket Community Pool, and the Early Childhood Center at Nantucket Elementary School continued as scheduled despite the shutdown.
