Millions of my fellow Texans were in crisis the week after Valentine’s day 2021. The weather was colder than it had been since Santa Anna marched his army to San Antonio, and the whole state was experiencing blackouts. But I was lucky. I had an exact record of precisely when the power shut off and was restored throughout this whole ordeal. How did this help me? It didn’t. But it was nice to know that my power outage notification system was working as intended.
