I kind of see your point but it's the wrong phrase. It's not a runtime dependency in a technical sense.
see now you're just splitting hairs and getting into philosophy. if your website will be stale tomorrow because you can't update it today, then that is a runtime dependency imo.

Why it is down tomorrow?
(Hint: sans hug of death, because a runtime dependency brought it down.)

Incorrect. You need build-time dependencies to change an application, and runtime dependencies to run it.
Deploying/scaling is somewhere in the middle.
If Github being down means you're not fixing your site today, I'd call it a runtime dependency.
