It is little known that many 'connections' run thru 3rd world countries, where poor folk are hired for minuscule wages to hold some of the more flimsy wires together. If one of these guys scratches his nose and lets go for a second..(or worse, collapses from hunger).. many bits of data can fall out the end of the wire before the ends can be reconnected!

(I thought I'd spare you the technical explanation, John....no, no...don't bother to thank me..)
