Welcome to 2015! or well, 2000-ish. Getting close to two decades we have been trying to explain to ISPs that the biggest cost in IPv6 is not so much the hardware (gets replaced during standard hardware upgrade cycle), or the deployment (roll-outs can go very very slow), but the training of their people who are answering the phones. Many ISPs have not even bothered looking at upgrading their hardware or at least demanding everything new they buy supports IPv6, let alone rolling things out and definitely did not bother with training their personnel to know about IPv6. The fun thing is, they could have a small IPv6 taskforce and put a note at the phone dudes desk: if you hear "IPv6" call the IPv6 taskforce. But clearly, they don't even invest in that.... and there really is no time left to start now, hence they have to do everything lots of folks have done slowly in the next few years, way too late, way too slow and also more importantly: not already having more than a decade of experience in operating it all.
