I edited zonemake and we don't publish AAAA records for our services any 
more. I don't know if this is going to be a real outage or whether it's 
been made as an advisory notice, but I'll turn AAAA records back on in a 
couple of weeks.

Presumably IPv6 packets sent upstream will just be dropped once the outage 
starts; I'm not sure what the best way is of avoiding long timeouts before 
fallback to IPv4. So I put it on ServerFault. We might have an answer by 
the time the outage is over (the current winner is "bring up some IPv6 
tunnels and then 1:1 NAT your ranges").
