Allow-List Recommendations for Traffic Steering Appliances or SystemsIssue When implementing traffic steering exclusion policies, certain services rendered by ServiceNow instances may not correctly function if the service is not on the allow-list. For example, if api-appsee.service-now.com is not on the allow-list, services directing to this URL will not properly function.CauseTraffic steering systems may only allow services configured in the allow-list. ServiceNow utilizes many different services that may change over time and product releases.ResolutionThe recommendation is to configure traffic steering appliances to allow all services, *.service-now.com. ServiceNow's services can and do change with updates and product releases. Allowing all *.service-now.com will permit all services that come through ServiceNow's datacenters.
