Coming back to *my* original point ... My first instinct was curiousity, 
and my second merely trying to decide whether it was worth the pain of a 
call to the iiNet helpdesk. I wasn't trying to troubleshoot someone 
else's network, just working out whether *mine* needed troubleshooting.

If there was some more general outage, there wasn't much point in me 
making any calls ("did the bits move for you?" is a valid question). If 
there's a more general ISP-specific outage, probably ditto. If there's 
some weirdness purely in my network, then I find out by having people 
say "nothing wrong here", and I get fault-finding.

I see very strange things happening on home networks - I guess anyone 
fault-finding does. As a pertinent recent example: after a reboot, but 
*not* a factory reset, my wireless AP made some decisions without me - 
it wouldn't let the laptop login (using a saved profile previously 
working); but more importantly, it started arguing with the ADSL modem 
about who's allowed to issue addresses. The fault-finding wasn't easy, 
only because the cause was so unexpected; and in the meantime, the 
behaviours looked for all the world like something happening at or 
beyond the ISP.
