Microsoft developers found a way to do it, without having to make any compromises or impact user-visible performance in any way.

Their brilliant trick to achieving this -- wait for it, it's so simple -- was nothing more than simply... sitting in the same building that Bing is served from! With a mere 1ms latency over 100 Gbps fibre from their office to the Bing servers, there's no pesky latency or packet loss to interfere with the instantaneous UX response times and deterministic behaviour.

Those pesky users are just "whining" and need to learn to sit at Redmond, just like they do.
