Chanhassen Dinner Theatres Hit by Norovirus Outbreak and Cyberattack
Chanhassen Dinner Theatres in Minnesota has canceled additional performances this week following a suspected norovirus outbreak among cast members and a cyberattack that disrupted its systems. The Minnesota Department of Health (MDH) is investigating the illness, which aligns with norovirus symptoms, while the theater follows MDH disinfection protocols.
On Friday, the venue’s computer network was targeted in a cyberattack, forcing systems offline. Officials are collaborating with experts to restore operations securely. Last week, performances of Guys and Dolls on May 15–17 were canceled, and now the May 19 evening and May 20 matinee shows have also been called off. Affected ticketholders will be notified directly.
Theater president Tamara Kangas Erickson emphasized prioritizing the health of artists and the security of systems before resuming operations. The venue expressed gratitude to its community for their support and apologized for the disruptions.
