Or that due to the 7 second delay in the publish/activate and there being 31 days in july and august...and the old key was revoked 7 seconds before the new key became active? Which didn't happen because I did the alg 7 to 8 transition, so June/July/August ZSK started later, so ended a bit into September. Hmmm, this is interesting....Revoke doesn't exist in my older keys... Revoke only appears with old key and current keys. Wonder what caused it to appear Looks like when I suggested we change from annual KSK rollover to every 3 years (which was good, because the sysadmin in another department that interacts with our registrar...left and now those interactions are done through our business office because registrars also need to get paid every year....and that former sysadmin was the last to have direct spending ability, left over from when she used to be a manager. Hopefully in 2015 when we do our KSK rollover, they understand all the aspects of interacting with a registrar....beyond buying and renewing domains. And, perhaps someday fix the missing NS for some domains, or the incorrect glue for others.)... The dnssec-keygen calls acquired -A and -R switches. And, the intent was for -A to be +7d, but the d got missed....so that's why its 7 seconds after creation. So, can I just remove the Revoke line (is there an option in dnssec-settime to do this?) and have things fixed...or do I need to do some kind of emergency ZSK rollover to get things sane again? Though why is the only a problem with Comcast....the other report named Xfinity as the ISP, which is Comcast....
