One of our client’s data trends, from a specific vendor platform, was a data delivery rate of 250-milliseconds. Initially, the West Highland support team noticed an increase to 500-milliseconds in the delivery and the rate never returned to its normal speed. The data vendor was notified and dispatched the carrier to evaluate the problem. As it turned out, the culprit was a dirty fiber connection. West Highland resumed monitoring and saw an improvement to a 300-millisecond delay, which still did not represent the client’s normal performance. The carrier was dispatched again to clean the fiber, which ultimately returned the data delivery rate to its normal expected speed.


This type of event would never have been caught by the naked eye and would have continued forever with a 250-millisecond disadvantage over any other competitor, potentially causing the client to pay more for a trade.
