Following what it calls a “cyber incident,” the event ticket distributor Ticketfly took its homepage offline on Thursday morning. The company left this message on its website, which remains nonfunctional hours later:

Following a series of recent issues with Ticketfly properties, we’ve determined that Ticketfly has been the target of a cyber incident. Out of an abundance of caution, we have taken all Ticketfly systems temporarily offline as we continue to look into the issue. We are working to bring our systems back online as soon as possible.
