Malaysia ISPs always use better effort as 'explanation', but results from their best effort are so bad that services are unreliable and/or unusable.  In addition, cost of broadband in Malaysia is not low (absolute and relative to quality of services)

Made a complaint recently to TM regarding the slow international connection.

Think it's not right to post the CSO's email reply in verbatim, so I'll just list out the points.
- They are aware of the situation and they will always to their level best to provide the best service.

- International link performance is subject to inter-ISP connectivity.

- Very unlikely that any ISP can guarantee end-to-end performance to international sites

- They recognise their customer base has increased and are making continuous efforts to upgrade their infrastructure

- Their role is providing Internet connectivity and access but they are unable to guarantee delivery of contents and performance of the host which is not within their domain.

- Their international traffic management capability is designed to cater for all customers' requirements to ensure they have optimal experience using the Internet, and this is part of their network performance policy.
I'm very sure that they haven't catered for my requirements, and I have been having a sub-optimal experience using the Internet.
