Dear Jan Hugo, Indeed, around 06:50 UTC two of our controllers became unreachable. ("Controllers" are the machines that probes are continuously connected to.) They are in the same colo (not at the RIPE NCC), both were up and running otherwise, and no other servers were affected so we can safely assume that the colo lost its connectivity briefly. In these cases the probes will reconnect after a short time (your two probes are back too). Regards, Robert RIPE Atlas team On 2013.01.23. 9:03, Jan Hugo Prins wrote:

Hello,

This morning I got a notification that the probe in my datacentre is down. I checked everything and he looks just fine and is happily doing traffic. Then I noticed that the one behind my home fiber connection is also down, and that the starttime is about the same. Both of them at 6:56 this morning. Also checked that one and he is also doing traffic just fine.

Houston, do we hava a problem?
