For you DNSSEC nerds out there, root zone KSK-2010 is now revoked as of the publication of root zone serial number 2019011100. Goodbye 19036, hello 19164. (Thanks to @PacketPusher for Jabbering me the new key tag ahead of the zone's publication.)
Admit it, you thought there'd never be another episode...
DNS Name Collision #OARC29
A lot of folks at ICANN and Verisign did a lot of work to make this happen.
Many thanks to @NLnetLabs for being excellent hosts for the ICANN and Verisign teams here in Amsterdam to roll the root zone KSK! #kskroll

The discussion of safe root KSK rollover criteria will happen on this mailing list: mm.icann.org/mailman/listin…
I just posted "The Story Behind ICANN’s Decision to Delay the KSK Rollover" icann.org/news/blog/the-… #KeyRoll

Personally, I totally refuse to ever call it "GNU/Linux". There's only one person who really cares and I don't give a shit what he thinks.
Everyone is retweeting this but that's not going to stop me from retweeting, too.
