Who is Global Gateway? They appeared on a traceroute to google on a Spark ADSL connection.

So I was messing around today, and decided to do a traceroute to google.co.nz.

It went through about 5 servers that were all named things like ae8-10.akbr6.global-gateway.net.nz but slight variations

Then through 2 random IP addresses, and ended up at syd09s01-in-f3.1e100.net, which i assume is where google.co.nz is stored.

So who is Global Gateway? I tried googling it but found not much of interest (or that I could understand, not being a network engineer)

I did find however a site called stats.ggi.net.nz which when visited has the spark logo in the corner and a login prompt, which I assume is for Spark tech support as my Spark login didn't work there.
