Article calls Gizzard, "strongly consistent" Gizzard's GitHub page says, "eventually consistent"[1]. What?

Yes, I think the article got that wrong. You are right that Gizzard is eventually consistent. The storage engine for Gizzard is mySQL, so in the event you want to do some node-local indexing, you at least have mySQL's strong consistency, but you won't achieve it in the overall system across keys.
