I am very excited to announce that we have rolled out a number of our top-tier websites over IPv6!
Thanks to some extraordinary effort by our Network Operations team, our PHX1 datacenter now has full IPv6 connectivity, and we’re taking advantage of it by adding v6 addresses for as many things in it as possible. Next up for them is SCL3, so we can do the same thing with sites hosted there.
You may recall we participated in last year’s World IPv6 Day. Some of our properties gained AAAA records back then, but over the year since they have all been removed for one reason or another… mostly because we only had IPv6 connectivity in one datacenter at the time, and it’s the one we’ve been vacating for the last few months.
Last year’s IPv6 Day was a trial run- the stated goal of the event was to have as many sites as possible turn on IPv6 connectivity for the day, with the understanding that they would likely turn it back off afterwards to fix whatever may have gone wrong. This year the event is returning, and plan is to turn it on and leave it on. Like last year, Mozilla is planning to participate as much as we can. This time, we’ll have a much larger collection of IPv6-enabled sites.
To that point, I am proud to announce that the following sites currently have full IPv6 connectivity, as of this week:
Several other (smaller) sites have working IPv6 connectivity as well.
Additionally, the following sites have partial IPv6 connectivity, meaning that IPv6 works in some regions but not others:
The chief culprit holding these back is that they’re hosted (or cached) out of datacenters where we do not have production-ready IPv6 connectivity just yet. These sites will improve further before World IPv6 Day, and more will be added.
While we’re on the subject, you might be interested in an IPv6-related Firefox extension, of which there are many. SixOrNot is a popular one. Even if you don’t have IPv6 connectivity yourself, it will show you if the site is available over v6 or not, as well as the IPv6 status of any resources on the page (Webtrends, GA, Gravatar, etc).
Be on the lookout for future announcements as World IPv6 Day approaches!
