Correct Magffrey. I had a long conversation with Martin Haven a few months ago and he said most of the reason behind FOM only being able to stream so many onboards is because the servers they have can’t handle more than that amount at once. I suggested upgrading their equipment, but he never got back to me on that. Now that I know a lady actually employed by FOM, I’m spending a lot of time tactfully hinting at it! :P
Edit: But out of interest, where’d you read that? I need all of the information I can get because it’s one aspect of F1 that intrigues me.
