NextDNS Scenario

Hello, we would like to use this solution professionally but we have some questions about how DNS filtering works.

In a per-service deployment scenario using these commands:
 

Invoke-WebRequest -Uri "https://nextdns.io/download/windows/stable.msi" -OutFile "$env:TEMP\NextDNSSetup.msi"
msiexec /qn /i "$env:TEMP\NextDNSSetup.msi" PROFILE=PROFILEID UI=0 ARP=0

Invoke-WebRequest -Uri "https://nextdns.io/ca" -OutFile "$env:TEMP\nextdns.cer"
certutil -addstore -f root "$env:TEMP\nextdns.cer"

In the event of a shutdown of services at NextDNS, would traffic be completely blocked or would a solution be put in place to guarantee operation with a backup secondary DNS from Google for example?

 

Is my traffic completely blocked if my service can no longer respond to requests submitted?

    What do you mean by shutdown of the service?

       Your services no longer work, your DNS can no longer be reached. So our requests are no longer translated?
      So traffic is no longer possible?

       our infrastructure is built in a way to ensure this can never happen with multiple network paths for primary/secondary IPs and automatic failover between PoPs. If your network can still not reach our DNS infrastructure for some reason, it would be unable to resolve DNS. There is no automatic failover on another DNS service.

    In our environment where we manage a computer park remotely, a domain name resolution problem would block all our machines.

    In another scenario NextDNS closes what would happen to our stations when your services are stopped.

    Thank you again for your answers, we just want to ensure that our park is not cut due to an impossible resolution.
    A modification after an incident in offline mode would be unimaginable
