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.
