What ever happened to glue records?
One of the things I noticed when I was fiddling around with daedalus the other week, was that when I had everything stopped, linux.org.au seemed to stop resolving (and therefore semi-important things like ftp.au.debian.org, which is a CNAME to mirror.linux.org.au
This made me very sad, because I'm always harping on about BCP 16 when I see other sites go down because all of their name servers are on the same subnet.
Now that wasn't the reason for this particular "outage", though. It seems that because one of the name servers is russell.linux.org.au, and there's no glue record for this host on any of the .org.au name servers, I don't think russell is seeing any DNS traffic at all (perhaps only from resolvers that somehow already happened to have a cached entry for it obtained through other means than an NS query for linux.org.au)
So before I go doing any further disruptive maintenance on daedalus I guess I'll be needing to get a glue record for russell.linux.org.au. I'm surprised that searching Enetica's knowledge-base for "glue" didn't raise a mention of it. I would have almost thought that they could detect the need for a glue record when you're adjusting a domain's delegation, so I wonder if it's a failure of their domain management system, or a complete oversight. Maybe people just don't go sticking their name servers in the domain they're hosting any more.
