if you're on a fibre connection already, then you should easily be able to get a bigger pipe - typically with just a config change. If telstraclear dont give you a good price for a fatter pipe then talk to another ISP. I used to have a telstra fibre connection with CallPlus as the ISP and that was a lot better priced that using telstracear as the ISP. I believe that Orcon and others can also use telstraclear, telecom and vector fibre connections.
Callplus does route via the new Microsoft Peering Point at APE so your latency to singapore will be in the 120ms range and performance should be decent.
Thanks yeah we are on TelstraClear, shouldn;t be a problem getting a bigger pipe as we have done it a couple of times with them in the past and yeah its a config change. Our problem is our firewall/gateway is heavily loaded so need that replacing as well as its causing a bottleneck so we dont get our full internet speed anyway thanks to the hit on the http proxy we have. TelstraClear are pretty expensive anyway so we will be shopping around this time.
Thanks for the headsup on CallPlus too.
