The Sundance Film Festival has been hacked.

“Sundance Film Festival has been subject to a cyberattack, causing network outages that have shut down our box office,” said a spokesperson for the festival. “No further information about the attack is available at this time, but our team is working hard to get our system back up and running as soon as possible. All screenings will still take place as planned.”

According to the festival’s Twitter account, a cyberattack forced the closure of its box office on Saturday.

All movie screenings will go on as planned, according to festival organizers.

“Our artist’s voices will be heard and the show will go on,” the festival added.

The cyberattack occurred shortly after Chelsea Handler led a Women’s March in Park City to protest the election of Donald Trump, at around noon MT. Roughly 40 minutes later, online ticketing for future shows had been restored.

It’s unclear if the attack was related to crowds in Park City, holding empowerment signs and speaking out against Trump.
