I suffered a small problem on today's ride and had to limp back to base and then continue on a different bicycle.
Anyone got a spare roll of duct tape or a tube of superglue?

Looks like you've had a small stress raiser where the down tube and seat tube butt onto each other, and the crack (or whatever it was) just slowly got bigger up to a point where it failed catastrophically as a result of cyclical loading.
Pretty classical failure tbh - would look good as an example in a materials science textbook.
