List Methods in WCF Service

I am trying to troubleshoot a WCF Service.

Using http://data.regionhigh.net/MyService.svc/help  it shows methods A ,B 

While in  http://data.regionlow.net/MyService.svc/help it shows the methods A ,B,C 

Is it something that has to do with timing of deployment or am I missing something. The method C was added recently.

Any otherway to troubleshoot this
