This result in every page load making a DNS request. This is a questionable technical choice, especially considering HN's status as the SaaS mecca. So it begs the question: Why? If the goal is to be able to rapidly switch to cloudflare when under attack then surely a TTL of 600 or 60 would be sufficient whilst being more respectful of your visitors?
