Is there a list of external domains that Sitecore calls as part of normal operating?

Question

I'm looking to get a complete list of the URLs that Sitecore calls during normal functionality of the base product. We have a client's IT group that needs to whitelist the outbound external calls to allow them out off their servers/network. There are errors in the logs for some but wondering if there might be more and would rather perform the action once.

Example: discovery-ces.cloud.sitecore.net

It would be good to have a living document or kb article that showed the version of the software and what external domains are accessed.

UPDATE:

Response from support was:

We have asked our product department for the requested list and have got the following URLs:

• https://discovery-ces.cloud.sitecore.net
• https://ssl.google-analytics.com https://sdn.sitecore.net/
• https://apps.sitecore.net/
• https://raw.githubusercontent.com/Sitecore/help/release/...
• https://fonts.googleapis.com/css?family=Open+Sans:400,300italic,400italic,600italic,700italic,300,600,700,800

There are a few other components (like Sitecore.Social) that might call:

• http://www.linkedin.com/home
• https://www.googleapis.com/urlshortener/v1/url
• http://www.facebook.com/home.php https://plus.google.com
• https://api.twitter.com/
• https://ajax.googleapis.com/ajax/libs/yui/2.8.0r4/build/yuiloader/yuiloader-min.js

Answer 1

In Sitecore Installation documentation, I didn't find any specific document which suggest allowing access to any external parties. With reference to your question, Sitecore offers add on services on top of experience platform, such as Device Detection, GeoIP, Email Delivery and xDB cloud which have their own integration requirements. Below links will help you to configure your firewalls if you are using any of them.

XDB Cloud https://doc.sitecore.net/xdb_cloud/working_with_xdb_cloud/configuring/configure_your_firewall_settings_for_xdb_cloud

GeoIP Service https://doc.sitecore.net/sitecore_experience_platform/setting_up_and_maintaining/ip_geolocation/ip_geolocation/setting_up_sitecore_ip_geolocation

Hope this helps!
