NOT (necessarily) TRUE.
There is a segment of their cabling/equipment that is dedicated to you 
and your location and a problem there would affect only you.  It may be 
the carrier and not the ISP that is at fault here.

When I worked for one ISP we had one single location where our ISDN 
connection was very unstable. We had 6 ISDN lines here and one was 
unstable. Swapping hardware that worked proved the hardware was not at 
fault.  The telco claimed they had no problems, but the instability 
continued.  I was finally able to get them to put a sniffer on the line 
and they found they had a problem with the cable routing/length/loading 
that they then fixed and the problem was solved.
