I try to keep ahead on Station V3, but it doesn’t always work out that way. At most I’ve had a week of completed strips ahead of time, and usually it’s less than that. Last night was one of those “less than that” times, and as I was finishing up today’s strip, the power went out. A couple candles and a phone call to the power company later, I found out it was because there was a fire in the area (which turned out to be on Ash Street), and the power would be back on in an hour or so. Which it was, and I completed the strip (fortunately I had saved just before the power died), and it was up when it was supposed to be. Of course, I was just lucky the power was back on in time, and I suppose it points out the need to always have at least a couple days’ worth of completed strips uploaded and ready to go.
Or it could have just pointed out the need to have today’s strip done about five minutes earlier… 
(Or maybe that missing a webcomic update isn’t quite as big a problem in the grand scheme of things as somebody’s house burning down?)
