Google Public DNS
3 Dec
Google announces their DNS initiative: Google Public DNS.
I always thought it was kinda inconvenient that there’s a “DNS propagation” downtime. Looks like one of the things Google is doing is making DNS propagation fast and asynchronous to requests.
Google Public DNS independently resolves domain names and keeps the resolutions in the cache until their time-to-live (TTL) expires, at which point they are automatically refreshed. The cycle of caching and refreshing is performed offline, asynchronously with user requests, so that responses are almost always available directly from cache.
