Amazingly accurate comic from xkcd is amazingly accurate:
Some day I'll blog about the time a lib maintainer deciding to [literally] say [well, "post"] "Ho hum" about just such a dependency temporarily crashed a reasonably large company's deployment script, but that day is not today.
(Luckily it was reasonably easy to fix, but it certainly cemented my usual claim that, "If you adopt a third-party dependency, you should also be routinely submitting pull requests to it.")
