I am running a home grown automated trading system through a Verizon DSL (the broker is IB), which recently experienced a lot of disruptions. On a typical day the disruptions (which forced the Trader Work Station to reconnect) is more than 100 times. Is this frequency of the disruptions normal in your experience? I read that cable high speed internet is more prone to disruption as it is "shared". If so, then it seems that I am struck with the DSL.
