It's the network Captain!
I have worked with a lot of small to medium sized businesses who to varying levels have come to see their internet connection as somewhere between important to vital. As more and more services move to the cloud the network connectivity and availability becomes ever more vital. When things have gone wrong with the network - and they will - small companies have exactly zero leverage with the ISP.
It is not too bad when there is a clearly identifiable fault where for example there is a complete loss in connectivity. The ISP recognises there is a fault and gets around to fixing it. Where it gets very, very difficult is where there is an intermittent fault or a fault not easily identifiable as being with the ISP. In these cases I have seen ISP's disown the fault completely or provide the bare minimum effort to try and identify the problem.
For domestic users moving to the cloud is even more of a gamble. There's an intermittent fault with Virgin Media broadband connectivity at the moment where it looses connectivity for a few moments. It's a bit of a pain when your browsing the web but a page refresh is acceptable. However, even this occasional intermittent fault is completely unacceptable to my two teenage kids who loose connectivity to whatever on-line mayhem and violence they happen to be involved with at the time. As a customer I can report the fault but I certainly can't expect a quick remedy (but I can expect to be told to reboot the router every time I call).
All I'm saying is that as you move more services/data to the cloud the network connectivity is more and more vital. As a consumer or small business you have very little influence on the levels of service from your ISP. I might use the cloud but I will have a disaster recovery plan in place so that if I loose connectivity, I don't loose everything.
