My ISP still serves ads for all DNS failures. Also, their cache times are absolutely ridiculous. It makes remote web development completely impossible. Let's say I change the DNS on a new domain (which takes only a few seconds to propagate with InternetBS+CloudFlare). Yet, if I queried the domain one time where it wasn't live yet, that error is cached for almost a day, with no chance of purging it. So others can see/use my service, but I can't.
