Possible, yeah. The highest-throughput Go usage I'm aware of within Google is https://github.com/youtube/vitess, Youtube's MySQL load balancer: "a fundamental component of YouTube's MySQL infrastructure, serving thousands of QPS per server".
Not sure how that compares to Cloudflare's global traffic though, and what other high-throughput Go usages exist at Google.
