The London BGP tunnel-server is now live and available to choose when creating a tunnel. Again if you would like your existing account to use one of the new tunnel-servers, please delete your existing tunnel then pick the new location to create your tunnel on.
*REMINDER* - Deleting your old tunnel means deallocating your IPv6 blocks, and you will be assigned NEW allocations based on the tunnel server you pick.
Frankfurt's BGP tunnel-server should be live later this week, we are still waiting on the facility to rack the equipment.
