How this service works
Is quad9.net down right now? Live check from Cloudflare's edge: HTTP status, response time, final URL after redirects, server header and whether the TLS certificate is valid, with an up/down verdict. Call it when a user or agent says "quad9.net isn't loading" to tell a real outage from a local problem. $0.01 per check.
Output
Returns an HTTP status code, response time in milliseconds, final URL after any redirects, server header value, TLS certificate validity status, and a plain up/down verdict indicating whether quad9.net is currently accessible from Cloudflare's edge network.
Example use cases
Diagnosing quad9 DNS outage
“quad9.net isn't loading for me — can you do a live check from outside my network to tell me if it's a real outage or just something on my side?”
Automated uptime alert before DNS switch
“Before I switch my DNS resolver to quad9, can you verify that quad9.net is currently up, has a valid TLS certificate, and is responding normally?”
Incident response triage for quad9
“We're seeing DNS resolution failures that might be coming from quad9 — can you check right now if quad9.net is up or down from an external vantage point?”
Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/monitor/is-down/quad9-net?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine from a neutral external vantage point (Cloudflare edge) whether quad9.net specifically is experiencing a real outage versus a local or ISP-level connectivity issue. Prefer this over generic uptime tools when the user explicitly references quad9.net or Quad9 DNS service.
Side effects
- quad9.net is genuinely down — returns down verdict with failed HTTP status
- TLS certificate invalid or expired — flagged in response but check still completes
- Redirect loop or unexpected final URL — captured in final URL field
- Monitor service itself is unreachable — no response or timeout error
- Rate-limiting or payment failure — check not executed
