Got a pop up that Time Machine hadn't done a backup in ten days. Usually when that happens there's a little exclamation point in the icon, but nope, so just how I was supposed to know this is anyone's guess, unless I've missed other pop-ups. Sure enough it couldn't find the router, a typical problem - and why the typical problem? Because of damn Time Warner having gone down on January 31st for four hours. What else is new? I should just automatically check whenever it goes down like that. Luckily, I wrote up the instructions and have them saved, so it really only took a few seconds to get it to find the router - it's now preparing the backup.
