Certainly not easily. We looked into this during early days of JBS and 
there was no ready way to do it. If not impossible, the effort required 
was not judged worthwhile compared to other kinds of customizations we 
were working on at the time.

As a matter of design, we have not wanted to prevent pushes from going through due to an outage of the bug database. However, we may want to reconsider the design trade offs in this regard and perform such a check if JBS is available, but not block the push from going through if JBS happens to be down.)

I agree that would be a good feature to have.
