A classic story that bears reposting:
"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."

@noelle It's a fun story, but most of the details stated in there don't make any sense. Personally, i think the author shouldn't have framed a story that has about the scientific accuracy as your average episode of Star Trek in a context that makes it look like a factually correct anecdote.
@noelle from the top of my head:
- the author mixed up travel time for single distance with roundtrip time
- electronic signals don't travel at the speed of light but - depending on the medium, voltage, etc. - significantly slower. as a rule of thumb you can assume half that
- caching by network equipment will typically add significant amounts of time
- context switching done in a multitasking operating system can put processes to sleep several microseconds, increasing delay further.
@noelle don't get me wrong, the story is entertaining. and the morale (as i understand it) to follow evidence wherever it may lead is useful to any engineer. it's just so wrong on so many levels, that is makes me cringe.
@tauli You're nitpicking details; if that's enough to make you cringe, go ahead.
