Very interesting. I've been doing some digging with traceroute etc. to 
have a look at the SAT-3 usage. To start with, it appears that 
www.safe-sat3.co.za itself is using SAT-3 (of course ...).

Here's a breakdown of the end traceroute from Europe, N.A., Australia 
to the site. Note that the jump from BT's concert.net delay of 100 ms 
to telkom where it's 274 ms delay. Only 175 ms increase - that's not a 
satellite hop! The speed of light in fibre is about 200 000 000 m/s and

the SAT-3 is about 15 000 000 m long so that about 75 ms lost just to 
the speed of light. I suppose the other 100 ms comes from the repeaters

or something.

Key: (host-name) | (geographic location if known)
        | (latency in ms) | (transit provider name)

[... some other part of the world ...]
166-49-218-130.concert.net  | ?
        | 109 | BT-IGNITE-GLOBAL-BACKBONE
wblv-lir-1-pos-4-0-0.telkom-ipnet.co.za  | ?(South Africa)
        | 274 | Telkom SA Ltd. IPNET-INT
rndf-ip-er-1-fe-8-1-0.telkom-ipnet.co.za  | ?(South Africa)
        | 290 | Telkom SA Ltd IPNET-EDGE
intekom-34meg-gw.gt.saix.net  | ?
        | 281 | SAIX SAIX-SERIAL-S34
zeus.intekom.com  | ?Pretoria, South Africa
        | 274 | INTEKOM INTEKOM-MIDRAND-5
www.safe-sat3.co.za  | ?(South Africa)
        | 275 | Telkom SA Ltd. SAIX

It would be interesting to know if any of those hops will always be 
present in a SAT-3 transit .. I suspect that 
wblv-lir-1-pos-4-0-0.telkom-ipnet.co.za might be a good candidate. I'd 
like to know what those abbreviations - wblv, lir, rndf, mean. In any 
case, the easiest way to detect a system using SAT-3 transit is the 
latency just by using ping.

Some popular websites hosted in South Africa, ping test indicates
SAT-3:
     www.southafrica.co.za - ping min 318.1 - AT&T
     www.aardvark.co.za - min 273.0 - Telkom
     www.telkom.co.za - min 273.2
     www.gov.za - doesn't respond to ping. but second last step,
     gov001-4.cust-gw.jnb6.alter.net pings min 297.4 ms - UUNET

Probably not on SAT-3:
     www.ananzi.co.za - min 571.2 ms - MTN
     www.mg.co.za - min 610.5 - UUNET (alter.net)

I hope that other countries on the cable pick it up as quickly as South

Africa.
