Hello,
Are there any reports that could allow one to check the status of IPv6 connectivity in the WMF cluster? If not, could you let me know if IPv6 is deployed on all servers and if you consider it stable?
IPv6 is mostly deployed on a per server/service basis right now, but we do consider it stable. Unfortunately there is no way right now to check the status of IPv6 connectivity but there is a Tech Ops goal of better monitoring which includes plans to make IPv6 connectivity checking a first class citizen (same as IPv4)
I'm seeing huge variations in IPv6 performance when connecting to WMF servers, while the rest of the internet seems to work and I'm trying to determine if the problem is on my side, somewhere on the way, or in the WMF network.
Well tools like mtr or even IPv6 enabled traceroute could be of immense help there. I must say, I 've not found a performance problem in the IPv6 connectivity yet in the WMF cluster. Feel free to provide us with more information, though if you have persistent problems
