This is a most excellent place for technology news and articles.
I remember reading a story about an email server that was limited to sending emails within 150 miles. Through a lot of digging, they found it was due to an auto-timeout timer getting reset to 0ms. Anything further than 150 miles would cause a 1ms delay and thus get rejected for taking too long.
