I like YYZ so much I named a computer after it.
I like beer better, so that's how I name mine (though their names are secretly variants of %&#&*%^$# ). I was on a low budget project and needed to steal servers (I didn't have my own hardware money) and I found a full but disused half-rack in the server room. They had names like Thriller, Beat It, Billie Jean, etc. I stole them and renamed them with a nod to the real MJ. They became Left Hand, Wynkoop, Avery, Odell, and ... Coors. That last one was our old slow beast that everyone hated but was cheap and had huge storage capacity built in.
Back to the topic, the exact same thing happened to me a little over a year ago. Turned out there was a small crack on the edge of the lid that had gone unnoticed. That's when I fully switched from buckets to carboys for primary.
