Just went through one here too.
I thought it might have been just me but I live on a ridge above a little town here in the Hill Country and looked down at the town and not a light anywhere.
Came back on in about 20 minutes. But I have a fireplace and butane stove so I was okay.
Same here in western Houston, power back on after 15 minutes.
I, too, am in the HIll Country. I was just clicking on this article when the electricity went off.
