I have migrated my Telkom ADSL line to Afrihost because they are cheaper and I also get my data from them, much cheaper that Telkom but the line still belongs to Telkom. It is reasonably reliable, shuts down perhaps once per month for a few hours but is consistently below par speed at about 0,9Mbps. The other day I noticed it snailing along at a few bytes per second, but that was apparently a once-off (so far)
