The Hitchhiker's Guide To The Galaxy has the following to say about website error messages:

"Website error messages are typically boring, cryptic, and often undecypherable snippets of geek code that are used to inform a user that he or she has screwed something up. Often, this is completely untrue, as the fault more often than not lies with the webmaster for failing to check that the hyperlinks on his or her website had been checked, doublechecked, signed in triplicate, sent in, sent back, queried, lost, found, subjected to public inquiry, lost again, and finally buried in soft peat and recycled as firelighters.

"Of course," the Guide continues, "at this point you are left with only two options. (Three if you suddenly, and for no good reason whatsoever, decide to irritate a Vogon by feeding his grandmother to the Ravenous Bugblatter Beast of Traal.)

"Your first option: Panic, which as we all know is not entirely a good idea.

"Your second option: Don't Panic. As any well-travelled hitchhiker will tell you (usually in exchange for a free drink), this is the better of the two options. If you are kind (or foolishly generous) enough to continue to buy them free drinks, they will likely share with you, albeit in an admittedly drunken slur of mumbles and obscene gestures, that there are, in fact, only two other pieces of advice in the galaxy that could even compare in sheer practical usefulness to the aforementioned "Don't Panic" tidbit. First, never drink more than two Pan-Galactic Gargle Blasters unless you are a 30 ton mega elephant with bronchial phneumonia. Second, and most important, never forget your towel. It's a big galaxy out there."
