Have you tested out whether you can set region: eu in the config.yaml and have the events sent to the correct place? I think that is the primary use case here and it does not seem to be working properly for me.

Interesting, it works for me if I do these steps:

1. remove the old config file by running rm -r /path/to/.pdagent
2. to test add this line: s.logger.Infof("Server will be using this events url: %v", common.PdEventsUrl()) to the beginning of func (s *Server) Start() error in pkg/server/server.go
3. build the new pdagent binary with make build
4. run pdagent init
5. open the config file in VSCode: code /path/to/.pdagent
6. edit the region field to be eu instead of us and save the file
7. run pdagent server

When the server starts up I see this in the server logs:

2021-07-12T13:12:51.817-0400    INFO    Server  server/server.go:62     Server will be using this events url: https://events.eu.pagerduty.com

Are you doing anything differently? Would love to test you method out to see what's going wrong.

UPDATE: pushed a fix for this here -> 6a02985
