[gtld-tech] gzipped error messages served as zone files

Hi Joe, 

We are aware of this issue, and we are working to fix it immediately.
In the meantime, you should now see the latest available zone files for both TLDs.
Also, we are working with the registry to fix the AXFR transfer.

    Some recent CZDS zone file downloads were missing all zone data.

    Specifically, the gzipped files were not empty, but their content was error 
    messages, not zone file data.

    For example:

    $ gunzip < bayern.zone.gz
    ;; Couldn't verify signature: expected a TSIG or SIG(0)
    ; Transfer failed.
    ;; Couldn't verify signature: expected a TSIG or SIG(0)

    $ gunzip < jot.zone.gz
    ;; Couldn't create key icann-axfr: bad base64 encoding
    ; Transfer failed.
    ;; Couldn't create key icann-axfr: bad base64 encoding

    "Transfer failed" should be a dead giveaway that something went wrong.

    Can we please improve error handling on the portal side so that output of a 
    "dig axfr" to make a snapshot for distribution is only ever packaged up as a 
    .gz file for download by CZDS users if it at least has a valid SOA record in 
    its first few lines?
