UPDATE: DOTA 2 SEA SERVERS MAINTENANCE :
The Starhub connection is in place. This should address most of the issues to the Philippines, Indonesia, Thailand and some of Vietnam and Taiwan with regards to latency. As for lag/freezing, this is likely to be a different problem altogether.
Valve have gone through the past couple of weeks worth of reports, and all of the traces are now within 150ms, with the exception of a couple in Vietnam. The paths to some of the Middle East are still questionable, but people on Etisalat should get pretty good latency since they peer locally in Singapore with Starhub.
India is mostly ok with the exception of MTNL and BSNL. Both of these networks have issues with the way they advertise their routes. I will continue to work on improving these when I can.
The path from Telstra should be improved as well. This should come straight to Singapore via Perth rather than via Hong Kong.
Valve are expecting a couple more links to come online in the next few weeks, but Valve don't expect them to improve things a whole lot. There is a lot of fine tuning still to be done. But this will have to wait.
Thanks for your patience and assistance.
