Native IPv6 providers/datacenters list?

I want to make an informed response to a comment made by our
CenturyLink rep regarding IPv6, in the context of SAVVIS not
being able to provide IPv6 at their DC3 facility:

There is only a handful of carriers that can provide that
service today and CenturyLink (Legacy Qwest) happen to be one
of them.

Is there a list of native IPv6 providers out there somewhere,
particularly one that includes hosting data centers (e.g.,
SAVVIS), with which I could cluebat^Wshare with my rep?

Thanks,

I'm not sure about a list of facilities, but here's a start for transit providers who should be able to provide IPv6 connectivity:

I'll come out in public and say that sometimes a backbone supports it but the datacenter group does not. This is quite common core -> edge deployment strategy with network technology. Some technology can grow from the edges inward, but IPv6 is not a technology that does it [well].

I've been observing some big increases in IPv6 traffic (its no longer measured in Mbps as from years ago, but in Gbps). I'm waiting for it to approach a fair percentage of the IPv4 traffic but there are some big steps being made by the networks and edges to bridge this gap.

Avoiding providers that can't provide a complete [*] IPv6 routing table is recommended too. The wiki URL provided by Christopher states quite clearly the limitations of using certain providers...
