To use Cloudflare, you switch your domain's DNS server to them. If that broke, you probably can't switch out without incurring the usual DNS propagation delay on your nameserver. If DNS is up, you can change specific records to point to your origin or another provider instead of the proxy/CDN, provided that it can handle the load and doesn't need a setup similar to Cloudflare (i.e. repointing your nameserver).
