Fixing "Our Services aren't available right now" error on Azure Front Door

Fixing "Our Services aren't available right now" error on Azure Front Door Our Services aren't available right now - Azure Front door Problem: In one of the projects I am currently working on, we have deployed Sitecore on Azure PaaS infrastructure. In the past projects, I have used Azure Traffic Manager to route the traffic to the nearest geographical location and also able to control the traffic to specific web apps which in turn helped us deliver the promise of Blue/Green deployment.

Link to Question is below http://sitecore.stackexchange.com/questions/2850/is-it-possible-to-fetch-datasource-and-personalized-content-of-context-item As the quote above says, I got passionately curious to understand How Sitecore Stuff works behind the scenes for personalization by Conditional Renderings. So, I started digging and opened my favorite .NET Tool dotPeek So, here is the magic(read pipelines and processors) behind Conditional Renderings. For those who are not aware, Any renderings we add onto page resides in PlaceHolder. So, we will start looking from rendering them and go deeper. Though there is lot more that will happen ahead of placeholder re
