Quote from Kazak_Trader:
I am actually on Skype with my friend and I asked him the same question, since you bring up a good point. He says that he contacted CQG in Moscow about this in the spring and was told that they have reserve servers set up in the main financial centres (Singapore, Tokyo, London, New York, etc.)... about 20 in total. So in case there is a force-majeur incident like an outage, the data would automatically shift over to the next best alternative path using the nearest reserve server. With so many servers, it seems unlikely that a trader would be stuck without data, but who knows, that's just my take.
zenfire users aren't stuck without data either, and quite frankly, you won't find a data provider nowadays that doesn't claim to employ redundancy.
my main concern is that this sudden shift in opinion on zenfire coincides with cqg's market entrance on many popular retail brokers.
