[atlas] Probe 2285 is disconnected (Randy/Bainbridge Comcast)

Hi Randy

Not sure if it helps but once I had a similar issue where the probe was
getting disconnected after every 4-5 days. I could see probe was reachable
on the LAN and even had a smokeping instance pointed to it which was all
clean. My own internet behind the same network was working fine.
Eventually found that issue was with the Ubnt edgerouter which used tweaked
VyOS and in their latest version 2.0.8 it was breaking the secondary
routing tables running on the device after every 4-5 days of uptime. So
except the main table, rest all tables were in config but just didn't show
up in "show routing table X" output. Eventually downgraded the OS version
and waiting for an update in next release notes of the firmware update.
