Describe the bug
It looks like GitHub is not happy about Nix querying the raw nix-fallback-paths.nix file.
When I try to access that file (whether by running nix upgrade-nix, or from a web browser logged in to GitHub), I sometimes get a 429 "Too Many Requests" error.
Here's what it looks like when nix upgrade-nix fails due to this problem:
root@debian:~# nix upgrade-nix
warning: the group 'nixbld' specified in 'build-users-group' does not exist
warning: error: unable to download 'https://github.com/NixOS/nixpkgs/raw/master/nixos/modules/installer/tools/nix-fallback-paths.nix': HTTP error 429
response body:
429: Too Many Requests; retrying in 268 ms
error: syntax error, unexpected invalid token

root@debian:~# Even though the error message says it will retry, it doesn't seem to actually retry. For comparison, here is what a successful execution looks like:
root@debian:~# nix upgrade-nix
warning: the group 'nixbld' specified in 'build-users-group' does not exist
[0.0 MiB DL] verifying that '/nix/store/kwck2vdfdp2v4jr9c4daryyk9mlbx406-nix-2.24.12' works...warning: the group 'nixbld' specified in 'build-users-group' does not exist
warning: the group 'nixbld' specified in 'build-users-group' does not exist
replacing old 'nix-2.18.1'
installing 'nix-2.24.12'
root@debian:~# The source IP address making the request doesn't seem to matter, so it doesn't seem to be a case of GitHub throttling one IP.
Steps To Reproduce
Occurs randomly as described above.
Expected behavior
The command should work reliably.
