The best I can do is refer to this thread, which lists some data points:

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.

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.
