For some retarded reason of PTCL's own reckoning, my upload was downgraded to 1Mbps instead of 3Mbps. My line stats haven't changed one bit, but strange thing is they didn't touch the download, its still the same.
I applied for 8Mbps VDSL package and they put me on 12Mbps instead, so I asked them to revert me to 8Mbps package. Could this be the reason why my upload was downgraded to 1Mbps??? Even if they did, i'm still getting 12Mbps download speed which doesn't make sense.
