We are calling this issue resolved in Finland for now as we are starting to see our nets become unblocked. The only remaining net which is still blocked as of today is:

2a06:1301:4050:0200::/64

But we expect this net to become unblocked soon as well. Reach out to support if you have any questions in this regard.

We have yet to get a response from Google on the specific issue, but we have observed today that one of our 3 blocked IPv6 nets has started working and is thus unblocked. The situation is as follows:

Still Blocked by Google:
2a06:1301:4050:45::/64
2a06:1301:4050:0200::/64

Currently Unblocked:
2a06:1301:4050:0100::/64

We will update here once we know more.

We have finally found a promising way forward to resolve this blocking issue. Apparently all we need to do is tell Google what the correct geolocation is for our IPv6 ranges. This is done through their ISP portal, which we have done already but we are still waiting on a response from there / for Google to take action. We are hoping this will clear up any day now.

Small update from here: Google claims they will give us a response / clarification on this issue no later than January 30th - we can't do much else but hope they resolve the issue by then or at least explain to us what is going on so we can remedy the situation.
