Yeah I found the same on Hyperoptic in London. Works fine 99.9% of the time, but occasionally ipv6 drops until I restart the router/restart the WAN connection.

Which of course I barely ever notice because most stuff switches back to ipv4. I think unless we start seeing ipv6-only stuff this will be the case, there's really no incentive for a lot of testing/debugging on at least consumer ipv6 connections until stuff actually breaks. Would be cool if Google added a 'ipv4' warning to Chrome similar to how they do with HTTPS (maybe not as strong though). That would drive a lot of adoption.
