Hello Experts,
I have few doubts regarding the Upstream & Downstream CI , Can you please help me to understand this .
I have read the example of "EMAIL " service , But am confused about the upstream & Downstream CI.
As per the sysadmin guide , it is explained as : All the CI that are feeding data into Email are Upstream CI & All CI that are affected by the Email are downstream.
My doubt is : as per my understanding services like blackberry & windows mobile are using email service not feeding data , so if email service is down , it will impact the blackberry & Windows mobile server , so how that can be upstream?
Similarly how Email servers can be affected by email service , it should be vice-versa , if Email server goes it down , then it will affect Email service
Can somebody explain me , where am wrong here ?
