port klang user here. slowdown since 2 weeks ago and still is. it suddenly normal yesterday evening (sunday) at 3pm but start to slow back at 6pm. can't even dota without ruining the whole game. sad weekend.

speedtest is rated at 300kbps to 500kbps with upload not stably indicated. usually it doesn't even start testing at all. stuck at the beginning. weird.

from tm tech support they are doing maintenance affecting klang valley area. mine is back to normal for now.
