My Atlas probe (ID 14587) has been showing as offline since December 16th. I can see DHCP requests/replies, it ARPs for the gateway and I can see DNS requests and pings from the probe, and successful replies to all of this traffic being sent back to the probe. e.g.: 12:13:38.790096 IP 192.168.0.115.35404 > 217.146.115.154.53: 2+ AAAA? ctr-nue15.atlas.ripe.net.

I'm not sure where to go next with figuring out why the probe seems to have vanished. Any ideas would be greatly appreciated. Many thanks. -- - Steve
