Less than 24 hours left for World IPv6 Day
The announcement was a rallying call for adoption of the new Internet Protocol; now, less than six months later, participation has grown to more than 400 organizations. We believe this is an important milestone, as IPv6 is the only long-term solution to IPv4 address exhaustion, and its deployment is crucial to the continued growth of the open Internet.
About 24 hours from now, at midnight UTC on June 8 (Tuesday afternoon in the U.S., Wednesday morning in Asia), all the participants will enable IPv6 on their main websites for 24 hours. For Google, this will mean virtually all our services, including Search, Gmail, YouTube and many more, will be available over IPv6.
In all likelihood, you wont even notice the test. The vast majority (99.95%) of people will be able to access services without interruption: either theyll connect over IPv6, or their systems will successfully fall back to IPv4. However, as with any next-generation technology, there may be teething pains. We estimate that .05% of systems may fail to fall back to IPv4, so some people may find Google, Facebook, Yahoo, Bing and other participating websites slow or unresponsive on World IPv6 Day. This is often due to misconfigured or misbehaving home networking equipment, such as home routers, that can make a computer think it has IPv6 connectivity when in fact its not working.
Over the past few months, weve been working hard with other industry players to prepare. Operating system vendors and browser manufacturers have been releasing updates to resolve IPv6 connectivity issuesfor example, Google Chrome now incorporates workarounds for malfunctioning IPv6 networksand weve seen router manufacturers test their devices for robust IPv6 support as well. For our part, weve been busy adding IPv6 support to services that didnt yet have it, and fixing minor issues with those that did. And since the best way to find bugs in your services is to hammer on them yourself, Google employees have been operating in World IPv6 Day mode for several months now.
Weve also been thinking about how best to notify people who may have connectivity issues. To that end, weve run a prominent notice in Google Search for people who may not be able to connect, directing them to a new test page and help article.
