Faster surfing speed by next month? No, I am not referring to the much publicized NBN(Next Gen Nationwide Broadband Network). I am talking about the little known Singapore Public Internet Exchange – SGIX, which I found out from yesterday’s Digital Life.
In my opinion, the SGIX is a critically important public infrastructure for Singapore. We have been relying on the carrier-specific Singtel Internet Exchange for too long.
Why STIX Singtel Internet Exchange Not Good Enough
The problem with STIX is, if you have a server at a data center in Singapore which is not connected to STIX, the traffic will have to be routed to Internet exchanges in Hong Kong(HKIX ) or in Japan(JPIX) or California(Palo Alto Internet Exchange and Los Angeles Equinix Internet Exchange) before coming back to Singapore.
And if you are wondering why Singtel is not peering with other carriers, you might want to read this report: The Singapore Internet Peering Ecosystem
“The broadband eyeballs in Singapore are owned by SingTel and StarHub (which acquired the CableVision Cable-based Internet subscribers). There is no incentive for either of these two Tier 1 ISPs to peer freely.”
Typically, ping to a local server within Singapore is 30ms or less. But a ping will take 100ms or longer if it has to be routed to the nearest public Internet exchange in Hong Kong before coming back to Singapore.
I have been hosting some of my websites on a Rackspace Cloud Server which is located in USA. Average ping to this server is about 300ms, because of the ping latency, I wished I could use a cloud hosting based Singapore.
Last month, I bought a Voxel’s Cloud Server located in Singapore. Voxel servers are housed at Equinix Data Center at Ayer Rajah. I was expecting to connect “directly” to the local server.
But I was wrong.
After 3 days of persistent testing and submitting support tickets to Voxel, I was using SingNet broadband, I was still accessing my local sever at Ayer Rajah via Los Angeles!!! Here’s the traceroute:

Taken For A Ride Half Way Around The World
As you can see, SingNet sent me half way around the world before connecting me from Tampines to Ayer Rajah.
And a ping to the local server via this route took about 200ms, that’s nearly 7 times longer than I expected. Apparently, Voxel which uses PCCW network did not peer to STIX.
There is nothing that I can do but terminate the Voxel Singapore server because I am already using 2 different data centers in California, USA. It’s not Voxel’s fault, which is already a member of SGIX. It’s just that our public Internet exchange is not ready yet and has to rely on STIX’s peering.
Hopefully, with the launch of the 2 new nodes, at 1-Net and Global Switch Singapore, surfing to local servers will be faster and I can use any data center in Singapore without worrying of being taken for a ride. Otherwise, even if we have the NBN, accessing local websites will mean wasting time via Hong Kong Internet exchange or worse, like my case, via Los Angeles!
Here’s the list of the 14 SGIX members (as of 8 Apr 2010):
- 1-Net Singapore Pte. Ltd.
- Deutsche Telekom Asia Pte. Ltd.
- France Telecom Long Distance (S) Pte. Ltd.
- Infocomm Asia Holdings Pte. Ltd.
- LGA Telecom Pte. Ltd.
- MobileOne Ltd.
