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?
