No power to the modem. And no power to the power strip either.
Unplug the power strips from the outlet, reset the GFCI switch, plug the power strips back in. Eureka! Power up the modem.
Now, let's check connectivity once everything's fired up. ESPN, yes. LiveJournal and Google, no.
Ok, clear the DNS cache on the studio computer.
And now everything works here again.
Back upstairs to the office to get everything working there.
