...or try to use them but fail and fallback to IPv4 a millisecond later.

Almost right. If the browser thinks it has IPv6 connectivity it will try, and it will fallback to IPv4. The fallback to IPv4 will take something like 30-60 seconds though!

That's exactly the problem Yahoo faces. People with broken IPv6 connectivity will experience serious delays when visiting their site. This has withheld other large sites, such as Google, from running dual-stack before. A test done by the large German website Heise.de shows the reality is not that rough. During one day they enabled dual-stack access for their website. Among the approximately one million visitors, only five experienced problems due to broken IPv6. After this experiment they decided to simply keep IPv4 + IPv6 enabled. See http://www.heise.de/netze/meldung/IPv6-Tag-bei-heise-de-Erste-Ergebnisse-1081201.html

Of course this percentage will vary according to the demographic of a site so, as Heise has shown, the best way is to test it. On 8 June, 2011, Google, Facebook, Yahoo!, Akamai and Limelight Networks will be amongst some of the major organisations that will offer their content over IPv6 for a 24-hour "test drive".

Submission + - Don't Panic, it's Towel Day! 3

An anonymous reader writes: Today, as every May 25th, geeks all over the world celebrate Towel Day and carry a towel in honor of Douglas Adams. The popular author of The Hitchhiker's Guide to the Galaxy died in 2001 at the age of 49, but his work lives on. According to the book, a towel is about the most massively useful thing an interstellar hitchhiker can have. Hence its symbolic role in this celebration. This year, for the first time as far as we know, Towel Day is being supported by the British publisher of Adams' books, who organizes a photo competition.

Submission + - Mac users' Internet experience to remain seamless 2

At TypeCon2007 Microsoft and Apple announced they have renewed their font licensing agreement, giving Apple users ongoing use of the latest versions of Microsoft Windows core fonts.

Back in 1996 Microsoft started the "Core fonts for the Web" initiative. The idea of this initiative was to create a a standard pack of fonts that would be present on all or most computers, allowing web pages to be displayed consistently on different computers. While the project was terminated in 2002, some of the fonts defined as core fonts for the web have gone on to become known as "web safe fonts", and are therefore widely used by Internet developers.
