No IPv6 connectivity to LA data servers

For the last 2 months or so I have not been able to connect via IPv6 to any server on the LA data center.
It always connects to the “Home” (chat?) server with IPv6 but “World” always connects via IPv4.

However If I connect to any server on the Chicago data center it’ll connect via IPv6 for both “Home” and “World” without issue.

Now I have been in contact with the peering dept of my ISP for just over a week now and they can’t see any issues on their end.

I’m unable to locate any information online on what IPv6 addresses Blizzard uses on the LA data center (just ipv4 addresses) to do any further research.

Any help would be greatly appreciated!

Thank you - hope it gets fixed soon.
