So, appears cambiumnetworks.com <http://cambiumnetworks.com> uses
cloudflare for DNS alone. Cloudflare goes inaccessible, bye bye
cambiumnetworks.com <http://cambiumnetworks.com> and I assume cnheat.
sas.cbrs.cambiumnetworks.com <http://sas.cbrs.cambiumnetworks.com>
is the URL for the cnmaestro SAS URL.
cloudflare DNS tell us to go ask AWS DNS for how to resolve
*.cbrs.cambiumnetworks.com <http://cbrs.cambiumnetworks.com>, but
cloudflare tell us to only cache these NS records for 5 min.. so
there’s our problem.
5 min of cloudflare being unresponsive and we’re toast for valid
cnmaestro SAS URL resolution.

Our Google SAS also went offline. Whatcha wanna bet
CNMaestro hard codes requests to 1.1.1.1 to resolve SAS URLs?
Gonna have to do some tcpdumps to verify.
