Do you work for github or is there some other way to view commit hashes across the whole of github?

Also what happens if two unrelated git hashes collide on github?




I have verified the fact via ghtorrent [1] when the previous commit (with 12 zeroes) was introduced (Korean tweet with a simple script [2]). However I haven't verified the current commit yet, hence the "cursory" analysis.

On the git commit id collision, I don't know about the actual mitigation deployed in Github but they are certainly aware of the possibility [3].
