Basically though, they added quad-a DNS records to all of their servers. They then added the v6 addresses to their servers. Only… they didn’t configure their webservers to actually display the pages via IPv6. </p></div>

Similarly how that goal was tested wasn't incomplete - of course a ping to that server would work, so would a DNS lookup (good for IPv6 Day stats), but seems that "Ensure that HTTP requests can be served from the IPv6 addresses" was missing from the test specification.</div>

<div><br></div><div><br></div><div>Also, as their objective *should* be to maximize eyeballs to their content (irrespective of IP stack), proper project and risk analysis at the project planning and management stage should have pointed out that having a setup that prevents fallback to IPv4 is bad.</div>
<div><br></div><div>Then again, the response could be coming from some tech support guy who may not have been part of the project. But again in the spirit of running effective project - the last stage of an project should be "Documentation Review and spreading lessons learnt". So one of the project tasks should have been to brief tech support folks with the explanation (if there was one) for this weird behaviour.</div>

<p class="MsoNormal">I have to say, kinda disappointed to see this from a company as large as Yahoo who did such a good job in the world v6 day in promoting v6, because this kinda thing really hurts the deployment of IPv6, it makes people scared to move ahead and it’s not what we need. </p>
