Furl answers the question "is this URL serving the content I expect?" Sometimes, we might be asking a server that in the middle of being reconfigured, is crashing, is buggy, etc. - in which case it might RST the connection. In that case the answer to the question is "False" and not "BURN IT ALL DOWN!!"
