Google Public DNS now supports flushing cache from web

Dear users,

Google Public DNS is pleased to announce that we now support flushing Google Public DNS's cache globally for a particular domain/type at: https://developers.google.com/speed/public-dns/cache . If you suspect that Google Public DNS is serving a record different from that served by the authoritative nameservers, you can now use this tool to flush the domain/type out of the cache of all resolvers that are currently up and running.

To prevent abuse, you need to solve a captcha for the flush operation. Additionally, a domain/type pair cannot be flushed multiple times in a short time span. If someone else has just flushed a domain/type, your flush operation may fail. If you do believe that another flush operation is still necessary, please wait a few minutes before retry.

If you need to flush an entire zone (*. example.com ) instead of a single domain name ( example.com/A ), or if the tool does not work for you, please submit an issue ticket at

https://code.google.com/a/google.com/p/public-dns/issues/entry .

Thanks,

Shen
