@CW, when you have a moment could you look at my PM reply from a day or two ago. And if you can, mention the prices of your Business capped account?

International breakout costs are cheap. IPC is hellishly expensive. Caching something just moves it into your data centre, but to deliver it to a customer, you still have to move over the IPC last mile network, so the costs you save from caching are offset by the hardware, maintenance, and admin it takes to manage the caching servers in any case. It gives customers a better experience, but it doesn't drive costs down necessarily. It's interesting to see other network operators publicly state that caching will solve their IPC concerns. That's simply not how a network delivering their data over IPC works.
 
I saw my account got changed (activated) last night - how long does the line speed upgrade normally take?

Out of interest, how long does it take for an ISP to acquire additional capacity? I'm sure the ISP monitors the trend seen with new sign-ups and adjusts capacity accordingly, but if there was a massive surge of new users, how long would it take for an ISP to "get up to speed".

Ages. Telkom IPC orders take weeks to be fulfilled.

Yea but if the ISP's IPC capacity is running low (which is where the problem is coming in) caching it isn't going to make a difference. So in essence the ISP isn't really making much of a difference by caching locally and the end users will still experience high latency/slow speeds/packet loss due to little IPC availability during peak times.

I cannot disclose, but what I can say is we have a pretty cool agreement in this respect. We're pretty agile on increasing stuff.

I have no clue if you may answer this but for every 1Mbps IPC you have how much Mbps can you provide across users? +-?

I am not here to work out how much profit you make ... hell if you make millions and still provide a good product by all means. Just trying to get a picture of how much people really use

1Mbps of IPC = 1Mbps of bandwidth across your user base.


1Mbps of IPC plus 100 clients on 1Mbps accounts = 100 to 1 contention - and that's bad.
10Mbps if IPC plus 100 clients on 1Mbps accounts = 10:1 = pretty good.

Cannot disclose, I'm afraid. But you can work it out somewhat. ;)

I guess the contention ratio are each ISP secret ?

And currently because we have a much higher average usage userbase, because most of our customers come from mybroadband, we've been running at even lower contentions quite often. Which is why we encourage those referrals to friends and family. Hint hint, nudge nudge, say no more, say no more. :D

DP unit - congestion???

Uhm, a Crystalweb rep told me (on live chat) that my one line is behaving bad because it was on a different DP unit than the other line... Guess it was false information?

Yup. I reckon it's pretty much the differentiator between the ISPs. High contention ratio = afrihost = unhappy customers. Low contention ratio = CW = happy us :D
