[RIPE Atlas Ambassadors] Question of high availability for atlas via different ASNs

Hello, everyone!


Greetings from India. I am hosting RIPE Atlas probe at home for a while. I
have two connections - primary which is high capacity symmetric link and
secondary which is a low-end cable broadband connection. The core router is
Ubnt edge router and it runs "load balancing" to keep primary link as
primary and switch to secondary if the primary is down for more than 30
seconds. This setup works well for me but RIPE Atlas is not part of this
"auto switch" if the primary is down.



I wonder if it makes sense to add RIPE Atlas to it?


   1. It will improve my monthly availability report and possibly will move
   from 98% uptime (of primary) to 99.9% uptime (of both links) and that's
   actually real uptime on LAN.

   2. But it would screw up probe data as both networks are completely
   different and have different sets of upstream resulting in different
   routing preference to root DNS instances etc.


Also, does probe comes only if connectivity is switched? It's a non-BGP
setup and when I say "auto switch" of uplinks, it's basically switching the
default route from primary to secondary while keeping same private IP on
LAN side. Due to NATing, WAN IP changes in this scenario.



Curious to hear thoughts if I should or should not. Another way, of course,
would be to do it for a month and see data. :)



Thanks.
