My net is completely dead in CPT, having to write this on my phone using 3G. Seems no servers can be resolved, maybe a DNS issue.
We are undergoing additional network improvements to prepare for implementation of our SAT-3 link in Cape Town. This will give us even more international capacity and further redundancy on our network.
In order to carry out this change, some preparation work needs to take place tomorrow night. Our Cape Town IPC links will have to be taken offline for a short period. We will be routing all our Cape Town IPC traffic to Johannesburg at midnight, which will last for approximately 3 hours.
We will also use this opportunity to activate additional caching servers in Cape Town, which will reduce the traffic on our north-south links and further optimize network performance.
I was half-expecting my international traffic in Cape Town to go via SAT-3 this morning, but so far I can't see any difference in routing. (I can't see any difference in caching either.) I guess these infrastructure changes will only bear fruit further down the line...
Edit: I'm sure its no secret that MWeb will sign up for WACS bandwidth in Q2 2011:

They are very much alive and caching broken downloads as far as they go.Hi Gordon and all others with this question. The only change from last nights work which may have an effect on the customer experience was the Cape Town caching servers that were brought online, although I'm not sure if they've been taken live yet.

A friend of mine told me about 'mtr' linux app (see above output) to do trace routes / ping tests and it is really fantastic!
Thanks guys, I have added this info to the escalation.
