Finally, it took ages to get the details for the Globalcrossing IPv6 and the eXpress peering sessions. But they are live now and we'll just have to wait for the eXpress route-servers to pick up our prefixes. That should happen in the next 24 hours.
All we are waiting on our circuit to PacketExchange is the session for IPv4 from Globalcrossing.
Anyhow, this means, that we have 3 IPv4 and 3 IPV6 transit carriers now.
