Ang mga technical na tao maka gets dayun ani. Anyways, pa simplehon PLDT is not really giving out what we have paid for.
The international standard for Internet Service Providers (ISP) requires countries to have their own IX (Internet Exchange) point to allow faster exchange of local traffic from other local ISP customers. This is required so the traffic for that country can be shared freely from one local ISP to another with less hops, rather than having it jumped from other countries like U.S, Europe, Australia, Hong Kong, etc. resulting to low latency and broken connection. Using this system also costs less because ISPs using IX aren't required to pay anything unlike if data is passed from another third-party network.
Aside from using a unified IX, ISPs are also expected to pay for a backbone service from selected providers for outgoing traffic. In Southeast Asia, PACNET is the one in charge. Backbones are important because it let ISPs connect to mainstream internet, i.e: the world’s internet. In return, ISPs are required to pay PACNET for its service.
Below you will see how PLDT deliberately refuses to use an IX or at least, pay for a real backbone company to properly route all its data.
