Google and OpenDNS Work On Global Internet Speedup 151
Many users have written in with news of Google and OpenDNS working together on The Global Internet Speedup Initiative. They've reworked their DNS servers so that they forward the first three octets of your IP address to the target web service. The service then uses your geolocation data to make sure that the resource you’ve requested is delivered by a local cache. From the article: "In the case of Google and other big CDNs, there can be dozens of these local caches all around the world, and using a local cache can improve latency and throughput by a huge margin. If you have a 10 or 20Mbps connection, and yet a download is crawling along at just a few hundred kilobytes, this is generally because you are downloading from an international source (downloading software or drivers from a Taiwanese site is a good example). Using a local cache reduces the strain on international connections, but it also makes better use of national networks which are both lower-latency and higher-capacity."

Speaking of squid, its 2011, is squid ever gonna support ipv6? There's not much software out there that doesn't support v6, and squid is probably the most famous.

None of the above. It's a scheme to pass your IP address to CDNs such as akamai so that they can select an edge server that's closer to you. Absent this, CDNs select an edge server closest to your DNS provider — that's fine if you're using your ISP's DNS, but in the case of an OpenDNS or Google Public DNS, that's likely a poor choice.

Even if your first connection is to a server in Djibouti, you may be redirected
Which costs a TCP setup and teardown to Djibouti.
to a server in Canada, and then that one may again redirect you to a server in Sweden
