You have not seen the problems so I can understand your inability to discern the source of them. I too once made a living diagnosing faults in complex electronic systems.

In any complex dynamic system each piece must function properly for the system to work and intermittant problems are usually due to an unreliability in interactions between the systems.

Think for a moment what the internet is. It provides data transport from one place to the other. What can go wrong? Data can either arrive slowly, out of order, or with known bad or missing data. Thats it.

Now- Why should any of those cause charts and quotes to stop? Why should it *stay* stopped even when the connection resumes? Why should data taking .35 seconds to arrive instead of .2 seconds change anything?

Only if qcharts expects a flawless fast connection and flawless performance of the servers. I consider that the fault of the programmer- not the fault of the data pipe.

Look at it another way: If it were the fault of the ISP connection alone why would so many people see the exact same problem at the same time?

I strongly suspect that the problem is that the protocol between the qcharts program on the computer and the server is set up so that it only functions properly within a finite (and too small) response time. If the net connection is a bit slow or the servers are a bit overloaded the whole system collapses. Sure you can fix it by beefing up the servers and encouraging users to get tier 1 net connections, but it would be far cleaner to solve the root problem.
