Is there a reason why we can't just link to the Wayback Machine copy like you did here? 
 
I agree with that as immediate first aid. It seems that wikipedia practice now is to link to both the original article and to a copy on the wayback machine.

I've found some perhaps useful pages by searching for "Bug report writing guidelines" (with quotes).

It might be helpful to provide links to some well-written bug reports, and perhaps some that could do better.

with best regards
