We've had similar complaints. I believe the cable has only been partially repaired. May take another week or two before it's back to normal at a guess. (possibly longer)
However with local hosts you should hopefully be able to connect to ultrapeers or even those from USA or Australia. I guess it depends upon how much of Malaysia's bandwidth is routed through Taiwan. Suggests a bit of a problem with infrastructure doesn't it. If Taiwan goes down then much of Asia is affected.
