Outlets not working after space heater was plugged in
Officially, wiring is done in a tree topology - each segment branches off another.  However, in practice, most wiring is done in a vine topology -- they're all in a row. 

Either way... the problem is in one of two places. 


The last receptacle which works
The first receptacle which does not work. 


Fiddling with any other receptacles won't do a thing.  

That's because the problem is in the wire or the wire ends/splices.  Failure of a wire is extremely rare.  It's almost always where the wire connects to something else.  

The usual cause is a "back stab" wire connection into the socket: the kind where you jab it into a hole and the socket just grabs the wire.  Backstabs are legal way to wire sockets - one time - but they're not very reliable*.  It is much, much better to use the side screws. 

* Backstabs are made for a single use. If you pull the wire out, the spring is sprung.  Also, when you are shoving the receptacle back into the socket, forces on the wires can lift it off its intended contact area, or overload the spring and cause it to lose tension.
