@Prithvi Pollam , Purge requests take approximately 10 minutes to process with Azure CDN from Microsoft, approximately 2 minutes with Azure CDN from Verizon (standard and premium), and approximately 10 seconds with Azure CDN from Akamai. Azure CDN has a limit of 100 concurrent purge requests at any given time at the profile level.
From the question it looks like you have deployed Azure CDN from Microsoft which has purging capability at< 10 mins. This requires a deeper investigation, so if you have a support plan, I request you file a support ticket, else please do let us know, we will try and help you get a one-time free technical support. In this case, could you send an email to AzCommunity[at]Microsoft[dot]com referencing this thread and your subscription id.
