DonutDNS checks whether your DNS change has reached the world yet. Every lookup queries 24 sources at once — around 20 geographic vantage points and four public resolvers — and draws each one as a slot in a box of donuts. Same answer everywhere fills the box. Sources still serving the old record leave holes, so you can see propagation instead of reading it.
Free, no signup, and analytics that only load if you agree to them.
