We had an interruption of the Teton service for about 15 minutes around 4 PM US Eastern time today. We will have more details later. We encountered an event, we have never encountered before (in the last 17 years or so), a server shut down due to a multi-bit memory error in one of the DRAM modules. We are fully prepared for this kind of event and had real-time copy of all information another server and were prepared to failover, but we brought the server back up again. We likely will make a decision to failover to a backup server this evening during the CME downtime. Today we had installed another server in the Aurora data center, that we are going to use also for Teton order routing. each server will serve half of the users so an event like this, only half of the users would be affected. That server is not yet ready. We will have more comments a little later. You need to examine your orders and positions and make sure they are all as they should be. During this time, OCO and bracket order functionality would not have been working so make sure any orders that should be canceled are canceled and verify your Positions are correct. There is a very small possibility of an incorrect position quantity, due to a fill getting reprocessed if there was a fill event immediately preceding the up to 120 seconds before this server event. We will explain why that potentially can happen. It has to do with how redundancy is maintained, on the primary server versus the real-time copy on our backup server. There is a balance between maintaining high-performance, and redundancy which is rarely needed. We do have triple redundancy with Internet connections but none of that was useful in an event like this which is extremely rare and as we said, we have not experienced a server shutdown previously like this.
