The answer to why some of you are seeing different test results from each other is context: you, your location, and other identifying information they can use in their firewall rules. If you are testing with SMS, the carrier knows who you are. DDG is supposed to be user neutral, but the Azure server serving the Bing results may have some information such as location. I do not know the relationship between DDG and MS and what data is shared.
