How to rollback github repository to a previous commit?

Question

How do I revert my Github Repository on Github to it's previous state?
I had made some change and committed them to github, but now I want to undo those changes on github. How would I do that?

I tried doing git reset --hard 7727c5bfa99 but that ONLY changed the repository on my computer and not on the github website
