The change now is to ensure that we take custom URL as well for updating the deployment, this is required for hotfix deliveries for certain deployments - other than the community release. This commit changes the previous work d65a2c672518a8af5f37f07c3abf18222df1839a with newer set of requirements. Also deprecates PeerUptime()
