Cache:clear fails when github.com is not available

When github.com is not available, clearing the Symfony cache (php app/console cache:clear) fails with an error message as below. What's the reason to make a connection to github just for clearing the cache?

cache:clear does not only clear the cache, but also warms it up. You can disable this behaviour with --no-warmup

Thanks, I noticed the setting install_on_warmup to false in the config.yml solves the problem.

sp_bower:
    install_on_warmup: false
