GitHub Code Search was introduced in 2021 and made GA in 2023[1][2]. It's an improved version of the previous global search (aka across all repositories).

There must be some sort of IP/browser reputation check going on. For Firefox on Mac, I get this on a private window:

I'm not behind CGNAT and GitHub can pretty much assume that my IP = my user. The code tab you can't see without logging in though.
