It was, in fact, the power supply that crapped out over the weekend. Out goes the old one, in with the new and all seems to be well and back in top shape for the STLMedia Main System. Thanks for the cards and flowers.
And thanks to STLMedia VP, IT and Everything Else, Mrs. A, for unplugging and carting the box hither and thither and then replugging everything back into its appropriate places, allowing me to seamlessly resume the silly foibles of work as the true man of leisure and VP of part-time everything that I am.
Hey! Look at the squirrel!
