There's more than one, but if your device connected to the time server in Boulder, CO, and it was inaccurate, that could cause 2FA [multi factor authorization] to fail, since it can be time based. Anyway, just a quick note in case anyone experiences [or experienced] a WTF moment. The time server in Colorado went offline because of power outages, and they're working to get everything back running properly.
