Ian as an ex-telstra Tech Officer, and someone who now works in the Security Industry (ie plenty of clients who don't "stuff around with their internal wiring") I can assure you that there are in fact LOTS of ways for wiring to be effected:
moisture creeping during sustained wet weather, tarnish/corrosion in wiring connections, long term electrolysis, plastic creepage (an insulation issue), tight wiring contracting under severe cold .... this is not to mention the effects of rats/mice eating all the insulation, or weeing on unprotected copper / metal connections .... that's the simple ones to locate.
Don't get me wrong, I'm not siding with Telstra, they often try to get everyone else (like my company) to prove all of OUR gear first beyond a shadow of a doubt before they'll even have a look at things, I don't use their internet and never, ever have even when I was a staff member, etc - but wiring CAN and DOES develop problems "without anyone stuffing around with it" all across this country every single day of the year.
