Just to clarify re: the DCs - they did/do support IPv6, but actually getting the addresses we needed provisioned was kind of a pain. That was a blocker for a bit. There were some other factors on our side that contributed to the delay as well. It comes down to the fact that our priority has to be reliable and secure operation of the services we're already offering. I'm glad it's finally here though, and now Let's Encrypt won't be a blocker for someone else's IPv6 deployment!
