Ask HN: Why is ipq.co so fast?
https://news.ycombinator.com/item?id=1819075I've discovered http://ipq.co here, and I'm amazed by how fast the DNS record is available throught my company's DNS server. How is it possible? I've always been told that DNS propagation could took from 24h to 72h...I'd be really glad to know the trick to such blazzing fast updates!
