There was a site with stories like these somewhere, I sadly can't remember the URL any more.
I think the one that stuck out to me was the Soviet mainframe computer that would get weird bit flips almost every day, always at the exact same time. Somebody compared what was different about the days it didn't get bit flips on, it turns out those were the days on which a particular train didn't run, the computer was very close to a railway station. What train was it, you ask? The one transporting the (definitely perfectly safe to eat, definitely not filled to the brim with nuclear radiation) cow meat from Chernobyl. The radiation was intense enough to cause bit flips, I'm sure the quality of soviet components didn't help here either.
