I recently came across an interesting article https://icdst.org/blog/index.php/2025/11/17/global-teams-us-connection-for-ai-and-saas-testing/ and was very surprised at how different digital experiences in different regions of the world can affect the performance of technologies. The authors explain well that today's internet is not a single homogeneous network, but a collection of regional environments where services, cloud platforms, and artificial intelligence models work differently depending on location. This is particularly evident in the United States, where many products first roll out important updates, new AI features, or security changes — and that is where companies test their solutions first. Therefore, teams from Europe, Asia, or other parts of the world can easily miss key issues if they do not test their applications in the American environment. The article describes how such differences can manifest themselves in AI behavior, network delays, or even security rules, which is why connecting through the US or testing with American servers has become an important part of QA for global teams.
