We checked our logs and there was no problem within our infrastructure at that time. There was no problem, from the CME either. None.

The main point is of what we said is there was no problem at all from the CME. We would see indications of that. It does not exist. And there was no indication of a processing problem with the CME MDP feeds. One good indicator of that is packet loss. There is 0% packet loss. Not a single packet loss. And we are processing many billions packets in a day on a single server, no problem at all.

The CME is not going to say anything about CQG. We have no idea, what this alleged problem was. We see no evidence of it.

There was not a single packet lost, 2026-05-28 across all three of our primary CME market data servers. And no significant lags. None observed at that moment.

So the issue must be due to external Internet connectivity.

There is no mystery here. We explain why these issues can happen here:
Prices / Data Falling Behind: 4.21 - Why a Data Feed Stops or Becomes Delayed

It is massively more likely that the problem is simply between the Internet connections that we use, and all of the public networking between Chicago/Detroit to Europe which goes through all of the paths of communication , Shared connections and equipment all the way to your home. You cannot ignore that.

And you cannot rule out the processing speed, of your own router.
