Pacing in my office this afternoon, talking with my dear old mother on my cell phone; I happened to observe a brief power outage. A bump, or surge, if you will. It was a loud buzz (no transformer around me that I know of), lights went out, and strangely enough it knocked out my cell phone. I couldn't get a signal on it until I reset the phone... Now what on earth could have caused this? Everything came right back on afterwards, and all is back to normal, but I have never heard of cell phone interference from a power outage before.
