Average International Packet Loss (%) - 0.053
Telkom liars said:Average National Round-trip latency (ms) - 16.43
Here are some international pings from UK to SA:
www.mybroadband.co.za
Minimum = 183ms, Maximum = 186ms, Average = 184ms
www.news24.com
Minimum = 158ms, Maximum = 162ms, Average = 159ms
www.kalahari.net
Minimum = 158ms, Maximum = 166ms, Average = 161ms
www.iol.co.za
Minimum = 159ms, Maximum = 172ms, Average = 165ms
www.webafrica.co.za
Minimum = 162ms, Maximum = 184ms, Average = 170ms
Don't see why SA outward ping times should be any different, isn't there only 1 cable?

Ping statistics for 212.58.254.252:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 192ms, Maximum = 193ms, Average = 192ms
So how does that work? I get say 20ms local + 150ms international to SA, for a 170ms total. You get about the same in reverse. But everyone is talking 300ms+ international pings, so how can Telkom say local is 17ms? More like 150ms+ on local.

ICASA was contacted for comment but, despite numerous attempts to get feedback from the regulator about the problems surrounding the ADSL Regulations, they remained mum on the issue.
