On MWEB’s peering war

A number of articles have appeared on Mybroadband about MWEB’s strategy to force MTN, Vodacom and Telkom to peer with them. Two comments: MWEB already peers with MTN. Here are the two hops between their networks1: 6 g-0-3-vic-jinx-2.mweb.co.za (196.22.163.1) 7 mtnns-2.jinx.net.za (198.32.142.31) I think what MWEB probably means by “transit” is that MTN charges them [...]

Myth of the greedy broadband customer

At yesterday’s Mybroadband 2010 conference, there was a panel discussion during which the topic of capped versus uncapped broadband was raised. Murray Steyn, the panelist representing VOX (an ISP that doesn’t believe quality uncapped broadband is possible) used the following analogy to illustrate his point: Providing uncapped Internet is like inviting 10 buddies to a [...]

ZaCon II and generosity

Today I attended and presented at ZaCon, a local information security conference, with a difference: ZaCon exists without funding (on purpose, don’t offer) or any frills that would make you want to attend other than a passion for infosec.

Localloop.co.za now locally hosted

One of the weird ironies about this blog has been that although it is focused on networking in South Africa, the web server hosting it for the last ~two years was a Linode.com virtual machine in New Jersey, USA. The server’s IPv6 connectivity was via tunnel to HE.net in New York. Now, thanks to the [...]

The smart phone I would want

Until I can use the same software I use on my two computers, on a mobile phone, I don’t consider the “smart phone” to be a general purpose computing device. Paul Graham has a similar metric, he wants the device to be capable of hosting it’s own development environment. Graham, among many others, has done [...]

Open access consumer broadband in South Africa

An open access network (OAN) is a horizontally layered business model for telecoms that has some interesting advantages. It is typically implemented by separating physical infrastructure from services. This creates a virtual market place, where end users have a choice of multiple service providers, and the service providers in turn are freed from having to [...]
