• Introducing AWS Cloudfront for network traffic management

  We will adopt AWS Cloudfront for network traffic management from Feb 1, 2023. As a result, our IP addresses (which have been static to date) will no longer work as a way to reach Connectivity APIs. Connectivity domain names will instead automatically resolve to various IPs owned by Amazon. If you are currently applying any IP-whitelisting, this will need to be removed as soon as possible. It is critical to reach us using DNS lookup according to best practices.

  You can validate and verify that no unusual DNS setup or static IPs exist in your system with the following new domain names. These two domains are already working in our new AWS Cloudfront setup:

  • supply-xml-migration.booking.com
    
  • secure-supply-xml-migration.booking.com
    

  For more information on the change, see Introducing AWS Cloudfront for network traffic management.
