Still one of my favorite internet things: The case of the 500-mile email.
I was working in a job running the campus email system some years ago when I got a call from the chairman of the statistics department.
“We’re having a problem sending email out of the department.”
“What’s the problem?” I asked.
“We can’t send mail more than 500 miles,” the chairman explained.
I choked on my latte. “Come again?”
“We can’t send mail farther than 500 miles from here,” he repeated. “A little bit more, actually. Call it 520 miles. But no farther.”
“Um… Email really doesn’t work that way, generally,” I said, trying to keep panic out of my voice. One doesn’t display panic when speaking to a department chairman, even of a relatively impoverished department like statistics. “What makes you think you can’t send mail more than 500 miles?”
“It’s not what I *think*,” the chairman replied testily. “You see, when we first noticed this happening, a few days ago—”
“You waited a few DAYS?” I interrupted, a tremor tinging my voice. “And you couldn’t send email this whole time?”
“We could send email. Just not more than—”
“—500 miles, yes,” I finished for him, “I got that. But why didn’t you call earlier?”
“Well, we hadn’t collected enough data to be sure of what was going on until just now.” Right. This is the chairman of *statistics*. “Anyway, I asked one of the geostatisticians to look into it—”
“—yes, and she’s produced a map showing the radius within which we can send email to be slightly more than 500 miles. There are a number of destinations within that radius that we can’t reach, either, or reach sporadically, but we can never email farther than this radius.”
Here’s a FAQ that addresses some of the questions the more technically inclined among you may have about this story.
