So I could for a long time now spot public holidays, weekends, and general stuff on network graphs, but never did I suspect I’d be able to detemine lunch and tea times based on network traffic graphs! Anyway, check this one out:
VoIP Traffic Graph
One can clearly see the 10:00 tea time, then lunch at 13:00 and tea again at 15:00 before things start quieting down for the weekend at around 16:30. Surprisingly there is still a decent amount of activity for a saturday :).
Right, so I’m in the privileged position where I’ve received more bounces in a single day than I generally do in any given 6 month period. Thanks to Nashua Mobile. Why am I posting this here? Because I’ve phoned them twice now, I’ve been promised it will be sorted out, and yet, the bounces keeps coming…
Ok, so SAIX finally pushed me over my limits. I’ve actually had to go make code modifications to exim now to work around the fact that they’re issuing incorrect error codes for their particular errors.
How does one define broadband? Is it all defined around throuput? Latency? Between which endpoints? Using ADSL currently one can expect a local latency of around 30ms to anywhere within SA, and depending on whether you’ve got a SAIX (Fibre) or IS (both Fibre and Satellite) you can expect anything between 300ms and 800ms to international destinations (obviously depending on the exact geographical location and the type/distance of the peerings being used).
