The air spring next to your broken upper shock bolt looks to be waaaay extended, IMO. I know that shocks can break in half due to a ride height over-height situation. Maybe the upper bolt gave out before the shock broke?
If the airs spring is extended due to being jacked up in the air, that is another matter.
Either way, a broken shock mount bolt, top or bottom, is not unheard of and the prior post had a good remedy.
