As this forum likes to point out so often, the network operators make a lot of money by providing voice and data services.
So it stands to reason that the networks will do their utmost to make sure you can make a call or eat up your data bundle as quickly as possible. If you can't, there is a direct revenue loss.
I'm often amazed by some of the accusations thrown at the networks. For example MTN got accused of refusing to build towers in Constantia in the Cape (cellhell.co.za) and Vodacom had a similar accusation about coverage in Fishhoek.
Why would the networks intentionally not provide service?
So that's a good point of departure to discuss the problems one see on these networks as these problems do occur from time to time.
Sometimes things really just break. This is the nature of IT systems and no matter how much redundancy you build in, things can go wrong. And does. But again, when something is down, it cannot generate revenue so the intention is to make sure it does not go down and to get it up ASAP if it does.
Sometimes things perform differently at certain loads than expected. This can affect not only the network but also those who use the networks to provide services. Vodacom has such a massive customer base, for example, that no amount of lab testing can simulate the real world. And often we are among the first to roll out new features. So it does catch you sometimes. But again, once its discovered, all hell breaks loose till it's resolved.
Often there are external factors that contribute to service delivery issues. As mentioned above, lack of towers can be a real issue. If residents stop the construction of new towers, how can the service be delivered? Half the residents in Constantia stop towers going up and the other half accuses the networks of not wanting to put towers up.
The issues with back-haul capacity is one of the primary reasons this forum exists and the problem will be there for a long time still.
And during all of this the subscriber base keeps on growing. So it's a very difficult situation for everybody. Demand is still rising but the ability to service it cannot always grow at the same rate.
But, in general, I don't think there is a 'general network issue' at the moment. If there was, this forum would light up like a Xmas tree.
Can't speak for the other networks, but from the Vodacom sub-forum there is an increase in throughput complaints and we're busy looking into it. Otherwise, it's about the same as normal. Which does not mean everything is perfect.
I suspect a number of things (mostly independently) went wrong the last few weeks (from one network who did have a problem over a weekend to a bank that delivered SMS's late to the latest Idols fiasco) and the combination of these did create the impression of a 'general' problem.
