Some exercise require github to be responsive, and it isn't.

Example:

• https://coderefinery.github.io/git-intro/browsing/#exercise : searching for "salt" requires the forked repository to be indexed. This has taken more than 20 minutes for me to happen, people were complaining about this
• Also the network graph seems to hang sometimes, it's also been reported to be buggy-ish

Good points. Maybe we should search in a repo which has been created earlier and is already indexed.
