Number of places, including Eircom themeselves. Basically, in the
70s/80s, when they were replacing the phone network, they had the option
to buy copper, or thinner, cheaper nickle coated copper cables. Then, the
only disadvantage with nickle coated copper was that signal degradation
above 8000khz was quite high, once you started getting over 100m from the
telephone exchange - but people didn't mind.
ADSL is broadband - doesn't just use 3000-8000khz like modems/phone/audio
does. So, if your line is nickel/copper, then once you are 300 meters or
more from the exchange, the voltage required to make sure the signal stays
quickly approaches infinitly. And Eircom don't know whether to say
"Drop ADSL", "Drop it far from exchanges", "Drop it in places that have
nickel/copper wires" or "Provide the infrastructure, and do something like
the 'We don't support anything faster than 9600 baud anyway' thing they do
at the moment.
 for small, abeit still expensive values of infinity
