Just to touch base on last nights outage, there was a longhaul fibre break on the fibreco route between Cape Town and Johannesburg.
This affected both our international to London from Johannesburg, we were then hauling the international ourselves in fail-over. We then turned up transit in Johannesburg to alleviate saturation on our 2nd longhaul path.
The new carrier to London has scheduled changes to put us on redundant longhauls, which is what we agreed to originally. So this shouldn't really occur again, unless there is an undersea cable break.
