High latency to Singapore server caused by TPG routing

[Eric123]

@Shane @david64 @waynezth 

Found this link in the game forum:

https://forum.albiononline.com/index.php/Thread/175614-Australia-to-Asia-server-235-ping/

We talked to our hoster (GCore) about the high ping issues from Australia. What they found out is this: Australian internet provider "TPG Internet" is "announcing" (this is a technical term) their IP range in way that causes all traffic from Australia to Singapore (and the other way around) to be routed via the US, hence the ping is a lot higher than necessary.

The best course of action is for customers of TPG Internet to contact technical support directly. They should open support cases with the following information:

* they are playing an online game and have a very bad ping
* the game servers are located in Singapore
* the IP range of the game servers is 5.45.187.0/24
* problem is that TPG Internet announces their IP ranges in a way that causes traffic from AU to SGP to be routed via the US, for example 61.69.212.0/24, 123.243.158.0/24, 194.193.192.0/24 and others
* i.e. TPG Internet need to announce their IP ranges in SGP properly

Hopefully this will help!

The latency have just increased back to 250ms+ again.

Tracert from Gcore (AS199524) (game server host) and Arelion (AS1299) (Singapore Equinix SG1 snge-b5) (the other end of the connection between Perth and Singapore) to my current IP address shows routing from Singapore -> Japan -> US -> Japan -> Sydney ->Melbourne.

Just to add. Tracert result from Gcore and Arelion looking glass to my current local gateway (27.32.160.2) shows optimal latency (86ms), which again suggest TPG did not announces some of the IP correctly and causes traffic from AU to SGP to be routed via the US.

Arelion results:

Hi @Eric123

We'll chase this with your case manager and have him to call you within the day for further discussion.

Hi @BasilDV @Shane @david64 @waynezth 

Just got off the phone with the costumer retention team. The response I got was that TPG technical team assess that there is no issue with the service provided and everything meets there expectation. I was given two options to either stay or leave TPG. It's shocking that TPG do not even recognize this as an issue, nor have any desire to improve your network performance, despite all the evidence and troubleshooting provided by the customer.

It's sad to say after being a loyal customer for over a decade, but we will have to look for other providers if this issue cannot be resolved.
