CDK Global is experiencing a significant software outage that is expected to last several days, potentially extending until the end of June. The dealer management system (DMS) has been down since June 19 due to attacks, affecting numerous dealerships that rely on the software for their operations. CDK Global has communicated that the system will not be operational by Monday, and current guidance suggests it will take several days before services are restored. The outage poses challenges for dealerships, particularly those closing their quarter or year on June 30.
