I also signed up for Cloudfare but it doesnt seem terribly effective. I will test the service 1 or 2 days then leave it doesnt work well for me
Cloudflare won't do anything until your name servers have been updated. Depending on DNS providers this can take 24-48 hours assuming they update every 24 hours. Before you give up on it at least make sure it's actually working.
