One of the reasons for the delay was that one of our support engineers was unavailable this morning due to an Internet connectivity problem they had. Although they would have noticed the problem, they would not have been able to do anything about it themselves. The programmer responsible for this needed to be contacted.

One of our other programmers who does monitor the board for critical problems like this at 9:30 AM Eastern time, did not recognize this as a problem on one of our own servers especially being our server monitoring system did not report a problem and could not report a problem like this. He is one of our newer programmers. They are now aware of this.

Another one of our senior programmers who does check the board around the US open, was not available this morning. Ultimately it was them who resolved the problem because they are the programmer for the TICK. And it was their effort to improve the TICK which caused this problem. It was not completely reasonable for the other programmers to have taken other actions to resolve this, because a software rollback which would have been a possible solution, would have affected other market statistics calculations for the day.

We are going to patch in some data now for the TICK-NYSE to fill in the missing data for this morning's interruption.

While this failure does disappoint us being that it occurred and went on as long as it did, unfortunately scenarios like this sometimes do develop and even affects large operations. The NYSE recently had an outage which affected at least half of their trading day. That was also due to new software which was deployed, that had a problem with it.
