Apple, Google and Microsoft still don’t understand new TLDs

Kevin Murphy, January 22, 2013, Domain Tech

The world’s most-popular web browsers are still failing to recognize new top-level domains, many months after they go live on the internet.

The version of the Safari browser that ships with the Mountain Lion iteration of Apple’s OS X appears to have even gone backwards, removing support for at least one TLD.

The most recent versions of Google’s Chrome and Microsoft’s Internet Explorer also both fail to recognize at least two of the internet’s most recently added TLDs.

According to informal tests on multiple computers this week, Safari 6 on Mountain Lion and the Windows 7 versions of Internet Explorer 9 and Chrome v24 all don’t understand .post and .cw addresses.

Remarkably, it appears that Safari 6 also no longer supports .sx domains, despite the fact that version 5 does.

Typing affected domain names into the address bars of these browsers will result in surfers being taken to a search page (usually Google) instead of their intended destination.

If you want to test your own browser, registry.sx, una.cw and ems.post are all valid, resolving domain names you can try.

The gTLD .post was entered into the DNS root last August and the first second-level domain names went live in October.

The ccTLDs .sx and .cw are for Sint Maarten (Dutch part) and Curacao respectively, two of three countries formed by the breakup of the Netherlands Antilles in 2010.

ICANN approved the delegation of .cw in October 2011 and second-level domains there have been live since at least July 2012 (that’s when the registry’s site, una.cw, went live).

SX Registry’s .sx was delegated in December 2011 and sites there have been live since early 2012. It went into general availability in November.

Safari v5 on Windows and OS X recognizes .sx as a TLD, but v6 on Mountain Lion does not.

The problems faced by .post and .cw on Chrome appear to be mostly due to the fact that neither TLD is included on the Public Suffix List, which Google uses to figure out what a TLD looks like.

A few days after we reported last May that .sx didn’t work on Chrome, SX Registry submitted its details to the PSL, which appears to have solved its problems with that browser.

It’s not at all clear to me why .sx is borked on newer versions of Safari but not the older ones.

If the problem sounds trivial, believe me: it’s not.

The blurring of the lines between search and direct navigation is one of the biggest threats to the long-term relevance of domain names, so it’s vital to the industry’s interests that the problem of universal acceptance is sorted out sooner rather than later.
