From what I've read, Telkom were blocking some p2p ports & throttling p2p in the past but I couldn't tell you whether they're still doing it

Their Acceptable Use Policy is a bit vague...they may still be throttling.

Do you know any other people who are Telkom customers & can use LW without a problem?
