Changes in how People’s Republic of China ISPs route Internet traffic could result in disruptions in Google ads serving Mainland China.
In order to help ensure that publishers and developers who receive a significant portion of traffic from users located in China continue to have access to stable ads services, some ads traffic will start to send requests to an alternate set of domains.
What’s not changing
Geographically, routing for ads requests and responses will remain the same regardless of the domain names used. The domain name itself does not determine or alter the routing of requests. Whether a user is connecting through doubleclick.net or doubleclick-cn.net, the routing of their traffic remains the same.
To ensure and preserve the privacy of users, advertisers, developers, and publishers, the encryption and security of Google services will remain paramount — regardless of the domains used. Important to note that the domain name does not determine or alter routing of requests or alter where data is stored and no additional parties will have oversight or access to Google ads traffic.
