Hi,

Your probe is/was behind (at least) two levels of NAT, so anything is
possible :-)

More seriously: our controller in LA, which is responsible for your probe,
got disconnected around midnight CET, thus it couldn't report connections
from probes; this is why your probe was reported as "down". We reconnected
it some minutes ago, so these buffered messages could finally go through.

The reason you probe could still report measurement data to the system is
entirely different. We are in the middle of an internal structural change,
which allows us to report measurement data on a separate, more scalable
channel. Our controller in LA was the first one to be switched to this
method (just yesterday!).

We are migrating other (EU) controllers to this new method in the coming
days. Also, we plan to use this method for more messages in the future,
making the system more resilient against these disconnection hickups.

Hope that clarifies!
