 All of the 911 system is using this Microsoft, Microsoft Cloud, CrowdStrike software. So I have no access to monitor units, to the dispatchers. The computers are shut down and dispatched. So they're dispatching through the old Cardex systems, which was in place in the 70s and 80s. Just to give you a time frame of the technology we're using at the moment. The units that are out in the field, the ambulances, are usually tracked via GPS.
