Can anyone explain the difference between SAIX and IS. I know SAIX = Telkom, but does IS have their own backbone, if that is the case, then why do all the ISP's not go through IS?
IS do have their own backbone. SAIX additionally have access to the undersea cable to connect to the rest of the work. IS uses satellite connections to connect to the rest of the world.
No idea why IS not cheaper though
As for ISP's, well SAIX is cheaper and has lower international latency due to the undersea cable.
