description Google Public DNS Uptime Record Overview

The Google Public DNS is a free Domain Name System resolution service introduced by Google to improve browsing speed and security. It operates on a globally distributed network of redundant servers that automatically route user queries to the nearest data center. By implementing advanced load balancing and caching mechanisms, the service maintains a highly consistent uptime record and mitigates the impact of localized network outages or DDoS attacks. It is designed for network administrators and everyday internet users who require a fast, reliable alternative to their default DNS servers.

help Google Public DNS Uptime Record FAQ

Does Google Public DNS publish a 100 percent uptime guarantee?

Google operates the resolver on globally distributed infrastructure, but the free public service does not provide ordinary users with a contractual 100 percent uptime SLA. A catalog entry called an 'uptime record' should therefore identify its monitoring source and measurement window.

What addresses are used for Google Public DNS?

The primary IPv4 addresses are 8.8.8.8 and 8.8.4.4. Google also provides IPv6 endpoints and encrypted DNS through DNS-over-HTTPS and DNS-over-TLS.

When did Google Public DNS launch?

Google announced the service on December 3, 2009. Its stated goals included making DNS resolution faster, safer, and more reliable.

Does Google Public DNS block malware like Quad9?

The standard Google Public DNS service focuses on resolution security and does not act as a configurable family or malware-blocking filter. Quad9's filtered service and Cloudflare's 1.1.1.2 or 1.1.1.3 endpoints are designed for users who specifically want blocking categories.
