mail.yahoo.com, "missing A records" and squid proxy

we have a squid proxy set up as transparent.

a few days ago users started complaining because sometimes they would
get a message like:

We'll take a look at it for you.

Possibly. According to the RFCs that's a perfectly valid configuration,
but according to some pedantic anal retentives (hi, Greg!) it's not.

If one of those PARs wrote Squid, that could be your issue.

Fortunately, you have the source; check for yourself, and fix it if it's
true.

Well, you don't have to be much of a PAR to find a problem with this:

$ host -r -Z -t ns yahoo.akadns.net za.akadns.net
yahoo.akadns.net. 90000 IN NS ze.akadns.net.
yahoo.akadns.net. 90000 IN NS zk.akadns.net.
!!! yahoo.akadns.net NS host zk.akadns.net does not exist
yahoo.akadns.net. 90000 IN NS zh.akadns.net.
yahoo.akadns.net. 90000 IN NS zj.akadns.net.
!!! yahoo.akadns.net NS host zj.akadns.net does not exist
yahoo.akadns.net. 90000 IN NS zb.akadns.net.
yahoo.akadns.net. 90000 IN NS zi.akadns.net.
!!! yahoo.akadns.net NS host zi.akadns.net does not exist
yahoo.akadns.net. 90000 IN NS zg.akadns.net.
yahoo.akadns.net. 90000 IN NS zf.akadns.net.
yahoo.akadns.net. 90000 IN NS zc.akadns.net.
yahoo.akadns.net. 90000 IN NS zd.akadns.net.
yahoo.akadns.net. 90000 IN NS zl.akadns.net.
!!! yahoo.akadns.net NS host zl.akadns.net does not exist
yahoo.akadns.net. 90000 IN NS za.akadns.net.

This has now been fixed.
