How this service works
Is letsencrypt.org 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 "letsencrypt.org isn't loading" to tell a real outage from a local problem. $0.01 per check.
Output
Returns an up/down verdict for letsencrypt.org along with the HTTP status code, response time in milliseconds, final URL after any redirects, the server header value, and whether the TLS certificate is currently valid — all sourced from a live probe run from Cloudflare's edge network.
Example use cases
Diagnosing letsencrypt outage vs local issue
“letsencrypt.org won't load for me — can you do a live check from the internet to see if it's actually down or just broken on my side?”
Automated cert renewal pipeline check
“Before my cert renewal script runs, can you confirm letsencrypt.org is up and its TLS certificate is valid right now?”
Alerting when letsencrypt goes down
“I keep hearing from users that their certs aren't renewing — can you check if letsencrypt.org is currently reachable and returning a healthy response?”
Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/monitor/is-down/letsencrypt-org?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine whether letsencrypt.org is globally unreachable versus a local or ISP-level issue. It is specifically scoped to letsencrypt.org and provides TLS certificate status alongside HTTP reachability, making it ideal for debugging certificate renewal failures or letsencrypt service disruptions.
Side effects
- The check itself may fail if the monitoring infrastructure is unreachable, returning an error rather than a site status
- Cloudflare edge location may have different routing than the user's ISP, so a 'up' result doesn't guarantee local reachability
- TLS certificate validity reflects the moment of the check and may not capture intermittent certificate issues
- Response time reflects edge-to-origin latency, not end-user latency
