I have to disagree with the above two statements. It is great that you guys are accessible on a public forum like MyBB and I think everyone appreciates your effort here, but my point with regards to lack of formal communication is that not everyone of your business customers is a MyBB member and follows this thread and reads for feedback between posts (when I posted my previous question, it is now 50 posts later within 3 hours). My point is that Afrihost, despite being aware of IPC issues since September has at no point sent out formal communication to any of their customers about contention.
People like I chose your business product because of the higher SLA's over your consumer products. So either Afrihost needs to come clean and "pull an MWeb" and state that business products can not be used for VOD, streaming, gaming, torrenting, but receive prioritisation for email, HTTP/S, VOIP, VPN, SSH and other business specific protocols - which I think is already happening behind the scenes to a certain degree (with the difference that business typical protocols such as HTTP/S, VOIP, VPN still degrade due to load).
The other option you have is to bump up your monthly subscription, but then provide the service as advertised. It is very short-sighted to state that anyone can leave whenever they feel like and this is currently happening anyway. Your problem will not disappear as new users will possibly show the same behaviour, your revenue will diminish further and as we all know, just selling bandwidth is an unsustainable business and the likes of BitCo, CyrstalWeb, Neotel and Telkom have already started to reposition themselves.
To be honest, with most of the peering agreements in place and local CDNs such as Akamai and Cloudflare appearing, an appropriate caching infrastructure will shift certain traffic patterns to your caching providers provided that you have peering agreements in place. I for one found it a laughable statement that your network was strained due to the iOS update - even my poorly configured Squid proxy server caches all iOS, OS X and Windows Updates so I am surprised that neither MTN/Afrihost can manage this on their sophisticated network.
