If your trading strategy is simply arbitraging Chicago/London, it's probably ok if your link is even 50% reliable, if for that 50% of the time, it's significantly faster than your competition's data. London is going to get the information 10ms later anyhow, so if a packet drops, you can still execute the offsetting transaction, just at the same time as everyone else.
