Hospital IT is intense. Priority 1 overnight call about overhead paging system being down. Such a system isn't just for show; it's critical for patient safety. Think of code blue and other coded alerts. We all wear the codes on our badges so that when the overhead paging system goes off, we can reference which alert is being announced. It's really the most urgent alerting system in the enterprise, ahead of voice or mail or teams chats or P1 calls. It's beyond ultra critical, and much of it is analog because the bits need to be converted to sound waves. Super interesting system.
