About Quad9

Quad9 is a public recursive DNS resolver service and foundation, founded on 11 May 2016. It is headquartered in Zurich, Switzerland, and was initiated by IBM, the Global Cyber Alliance, and Packet Clearing House. Its official website is quad9.net. It is also known by the addresses 9.9.9.9, 2620:fe::fe, and the name Quad9DNS.
Quad9 is a free public DNS resolver based in Switzerland. This status page tracks whether its resolvers are answering queries as expected. If your internet feels slow or certain sites refuse to load, DNS is often the culprit. Here you can check for active incidents before changing any settings on your own devices.
Quad9 runs recursive DNS resolvers that anyone can use. The best-known addresses are 9.9.9.9 and 2620:fe::fe. The service also blocks domains linked to malware and phishing, which is why some sites may behave differently here than with other resolvers. Typical problems are slow responses, timeouts, or queries that return no answer at all. Blocked domains can look like an outage when they are not. Router misconfigurations and cached bad results cause a share of reports too. Start by testing with a different resolver to narrow things down. Flush your local DNS cache, then restart your router if the issue persists. The status page shows whether other users are reporting the same thing.
