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.

ISPs posing as Internet exchanges

An Internet exchange or peering point provides layer 2 switching to enable direct and efficient interconnect for parties who wish to enter into peering or transit agreements. You get a port and an IP, then you get to use one MAC address to exchange IP packets with other customers. So, back in the nineties, Telkom [...]

ISP Fail: FNBConnect and Internet Solutions. Who screwed up?

The /16 route being announced by First National Bank’s new IPConnect ADSL-based consumer ISP, FNBCONNECT (AS37028) disappeared from the Internet Solutions (AS3741) local routing table somewhere between last week Wednesday (2009/08/12) and Friday (2009/08/14). It seems their transit via First National Bank’s own network went down. FNB, in turn, buys transit via IS and MTN [...]

Observations on backup-only BGP multi-homing

Last year, I set up a backup Internet link for (my then-employer) the University of Cape Town. The university has it’s own class-B block of provider independent IPv4 address space, so this required Multiple-Links-Single-IP-Space style multi-homing.
