Default GFCI Protection Question ?

Concerning the normal GFCI protectors/modules:

Obviously they protect "downstream" like they are designed to.

But does this protection also extend "upstream" ?
If so, to where ?


No, it does not (generally) extend upstream (back to the source). If
such a device exists it is not common and/or I have not seen one or
heard of one.
