[atlas] An article/FAQ entry about probe troubleshooting

Hi all,

it seems that failing probes are getting more and more to be an issue,
possibly due to USB flash drive failure. I think it would be nice if
there was an article / FAQ entry with some official troubleshooting
procedures, so we could just send a link to anybody complaining about
non functional probe.

Is there something like this on the roadmap? Perhaps we as the community
could make something up:

 - how to check whether the port probe is connected to has proper IP and
DNS parameters and is allowed to establish a SSH session to TCP port 443
in the Internet (beware of DPI firewalls that allow HTTPS but not SSH
over 443)

 - how to check the LED status and the SOS list at the probe page (the
current LED explanation in the FAQ is too techy and even power users
like me still don't understand all presented states :) )

 - how to diagnose USB flash drive failure, how to force reformatting
the flash drive and how to replace it with a new one


What do you think?

Cheers,
