What is an upstream server ?

In what context did you read this?
Error 504.
If you request data from a server, chances are that your server needs to request that data from another server - which is 'upstream'.
There can be multiple upstream servers involved in responding to your single request
So, the fact that l'm using piefed, multiple servers are involved in responding to my request ??
