Les, let me clear up a bit on the Kenyatta University issue. Though their bandwidth is supplied by KENET using a /24 block from our /19 allocation, they are hosting their website with another ISP at the moment that is being supplied via Seacom bandwidth hence the reduction in the latency. The KENET block is 41.204.160.0/19 and KU's specific block is 41.204.168.0/24 . If you trace an IP from that block, it will pass via ABS satellite who are currently supplying our VSAT capacity.
However, we have been recently (last week) been supplied with a backup link via Seacom by our upstream provider (KDN) that we are currently testing so if you trace some of our blocks eg: 41.204.164.2, it will pass through a Seacom supplied link. As for Braeburn, I can tell from the IPs they are using that they are being supplied by an ISP that I know is live via Seacom. At the moment, KENET is only supplying Higher education institutions ie research institutions and universities so Braeburn being a school is not under KENET. We are to extend to schools in the future, but currently we have 43 HEIs live.
I hope that clears it up, feel free to reach me if you need more info
