I've had better months in my 21-year technology career,

Even with the outages that we suffered, our availability is still 99.1%, and the call centers were open to take trades during the outages,

The good news is we had no network-related outages - and have had none in recent memory,

Our notions of scale have been tested again and again, ... We must have transaction by transaction redundancy and reliability - and all this must happen automatically. These are big network challenges.

We have a lot of questions with the technology and the regulations themselves and until we see specifics on paper in a couple weeks, we really can't comment.

Once technology started to be viewed as something that could give a competitive advantage, it had to be closer to the business units to understand priorities.
