Hum.  Maybe it's something different about how you're doing DNSSEC than 
I am.

I have BIND managing DNSSEC for me via "auto-dnssec maintain;".  So I 
don't get .signed files.

I was just able to do the following:

rndc freeze $ZONE
rndc sync -clean $ZONE
rndc thaw $ZONE
rndc sign $ZONE

I did have to manually do the "rndc sign" for DNSViz to be happy with 
the new test entry.  I don't know if that's expected or not.

The new record showed up exactly as expected.

Granted, I only added an A record and didn't create a new sub-domain.

I don't have .signed files.

Does your actual zone file have the DNSSEC records in it?  That's where 
mine are.  I don't have a separate unsigned zone file.

I believe so.  Do you have a "managed-keys-directory" entry in your 
named.conf file?  (I do.  My .key and .private files are in the 
specified directory.)
