A blog post from the LinkedIn engineering page announces that they’ve permanently enabled IPv6 on their infrastructure. I am guessing they took a phased approach, with services migrated to IPv6 gradually until completion this weekend.. (or maybe this weekend marked the end of a week-long soak-testing in the live environment).
Whatever, deploying IPv6 in LinkedIn means that IPv6 only connected parts of the universe can now use the site. Indeed, even during testing, about 3% of users to the website were on IPv6.
In a similar way to LinkedIn, I urge providers and ISPs to join the IPv6 revolution.
