Why It Matters to Facebook
World IPv6 Day will allow us to better understand how our infrastructure and code perform under IPv6 while minimizing impact on our users. Since January, we’ve conducted several studies and tests of our own and have gained even greater confidence that our site is ready for IPv6. We anticipate that 99.97% of users will not be affected at all. The small number of users who may be affected may find that pages are slow to load and we are working to minimize the impact.
Of course, we will be prepared to address any issues as they come up. Our Help Center has instructions and more information for users who may be affected.
We are encouraged by the overwhelming response of the hundreds of major organizations who have signed up to participate on World IPv6 Day.
