The best I can do is refer to this thread, which lists some data points: http://mailman.powerdns.com/pipermail/pdns-users/2011-May/007719.html DENIC and SIDN (the .de and .nl registries) still measure PowerDNS at around 40%-50% of all their domains. You might also want to consider that SIDN and NIC.AT underwrote part of PowerDNS 3.0 development, please see the 3.0 release notes for more details. > Have prepped PDNS to replace our Bind instances however management have > raised concerns over moving away from the "industry standard", so have > asked for more justification on the change in software.

If your management wants assurance on PowerDNS performance & reliability, they might want to consider joining the other serious users that have taken out a support agreement with a 2 or 4 hour SLA which is available. I'm not sure if a lot of major users will chime in on the list - the larger the company, the less likely they are to share their details on the list. The largest PowerDNS deployments are around 8 million domains, and loads of deployments are million+. Measuring the 'company domain name' with fpdns is of limited utility - the company domain name itself is often not on the ISP production platform. fpdns also does not identify recent PowerDNS versions.
