All broadband providers apart from maybe a couple use Global Gateway for international data.
Snap Internet (who we changing away from) uses both global gateway and telstra's network for internation traffic, it's dynamic, so one minute you may be going through telstra and the next it's going through Global gateway.... we've been with Snap for around 6 mths and really do notice it when our traffic is routed through Global, we get packet loss and lag issues.
The only times we do not get packet loss or lag issues is when our data is being routed through Telstra.... (which is becoming less and less through telstra).
SNAP seem to be shaping as well.
....so we are changing back to Telstra this week.
it also seems when we are routing through global gateway, the sites we often go to are being blocked.... on Telstra, we get around 200 - 220ms ping to US servers, where as when we are going through Global, we get 300 - 350ms or worse with packet loss.
We are on max/max internet, connecting at 19Mb/sec down, 1mb/sec up.... so yes we do pay for our data, we aren't on a flat rate either, and are just around the corner from a new fibre box.
Advice to anyone who is a gaming enthusiast....
SAY GOODBYE TO GLOBAL GATEWAY AND HELLO TO TELSTRA (PDQ)!
