Hi

Below is an image showing the received messages every hour for the last 24 hours, 07:00 (utc) 24th Oct - 07:00 25th Oct. Red graph shows data received in cayenne, while the blue is my own mqtt subscription. It’s the same device, and the device sends every 5th minute.

Take a look at my next figure, same device as in the previous figure, data is colleceted via mqtt and shows received messages every hour for the last 30 days. _ **Ignore the period with zero received messages, that was local incident** _.

It could of course be my mqtt subscription service, but I don’t see any indicators of that beeing the case.

So, what have happened, since I lost less messages before, could it be:

- Related to the unstabilities ttn have had lately / due to the increasing load ttn is experiencing?
- A local problem of mine with unknown cause.

Is anyone experiencing the same?

See [backend packet loss](https://www.thethingsnetwork.org/forum/t/disappear-messages-in-the-app/31059/5). Had some issues with the UDP-connection, but still not clear if messages are lost in the connection or in the backend. referring to the Gateway logs Messages are acknowleged.
