Find the Site Outage!

So, yesterday Scalzi.com experienced a bit of technical trouble. Using the graph below, can you tell approximately when this trouble occurred?

Take your time. It may not be obvious at first.

I find charts and graphs confusing.

Yet they provide a comforting reassurance that others know what’s going on. Perhaps that’s why I voted for Ross Perot.

My site totals look like that, once you remove the two zeroes on the ends of the numbers on the vertical part on the side.

OK… once you remove the three zeroes etc….

I don’t seen an outage there, all right?

Everything looks alright to me.

While the gap between 1045 and 1315 is clearly long and troubling, I’d be much more concerned about the systematic outages every hour between xx45 and xx15. Whatever the problem is, it may be costing you up to half your traffic!

…Oh, you say, it’s just that the bars in the bar chart aren’t the full width of the bin. That doesn’t seem like a very good chart design. Here, the data is so regular that you can get away with it, because the viewer can deduce the bins and the bars’ relationship to them. But what if you have irregular binning? Are the bars aligned to the center or the beginning of the bin? What if the bins aren’t aligned to the graph tick marks?

And what does Tufte say?

Well, obviously it was at 14h, after all the Whatever readers attended the big 3-hour Worldwide Scalzi Fan Synchronous Meetup Lunch (with drinks) then came back and all hit the blog at the same time to see what they missed…

Just so you know what *really* happened.
