Hi, This is the second day that CME data is freezing. Occurred yesterday at the Open, today at the Open, and twice moments ago. Three connections (please see attached screenshot of IP addresses of the connections). 2 are connected to CME MNQ and 1 is connected to CME MES. Yesterday logged out/in that resolved it. The MES connection only exhibited the pause at the Open yesterday. Today it paused for a several seconds on the MNQ connections and then continues. It was quite noticeable. Could you please suggest how to resolve? |

Was it just the data that stopped? Are you able to interact with the system when this occurs? If you have not stopped restarted one of the instances where this occurred. Then please get us the message log by following these instructions: Support Board Posting Information: How to Post Your Message Log (Required In Some Cases) And tell us what time the issue occurred relative to the Global Time Zone set for that installation.

I saw the same behavior today at the open. Price freezes and goes in spurts for a bit. I had thinkorswim mobile opened up at the same time on my phone and it was doing the same thing as Sierra. So I concluded it was either a broader CME issue or on my end or somewhere in between.

Yes, just the data stopped. Yes, am able to interact with the system when this occurs. Okay, unfortunately did close those instances prior to seeing this response, but will send the Message Log and global time if it occurs again. |

I had the same issue on the NQ open. If it happens again, I'll save the logs

We do see clear indication of a problem. Substantial market data delays, exceeding 30 seconds sometimes. This was due to degraded Internet connectivity on our side. It did not affect all users. Only some users. It appears as though it was the Lumen Internet connection where the problem was. Hard to know that with certainty though. Unfortunately, these issues are just simply hard to avoid, Internet connectivity issues can just simply happen at any point in time. This is why we use many carriers, and users are distributed among carriers and servers. We will be adding another server in the Aurora data center and another carrier, and this was already planned before this incident. What we recommend you do if you have this problem is select File >> Reconnect. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
