Seen several people report that GitHub actions are failing because the caching service return 503. Github status still report that everything is normal
see also <a href="https://github.com/actions/cache/issues/820" rel="nofollow">https://github.com/actions/cache/issues/820</a><p>Looks like the package servers are having troubles. Apparently a workaround is to use the `cache: npm` parameter for the setup-node action. Won't help when you rely on other actions or docker builds etc.
