Is Letsencrypt Down?

The verdict at the top of this page comes from the latest poll of the official Letsencrypt status feed and refreshes automatically, so you are not looking at a stale cached answer. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead.

Check the component list on this page first to see if your failure matches a known outage. If it does, you can report the issue for other engineers, follow the incident timeline for vendor updates, and run any fallback your app supports until Letsencrypt recovers.

PulsAPI tracks Letsencrypt uptime over 30, 60, and 90-day rolling windows. The current 30-day uptime is 99.97%. The 90-day uptime strip on this page is public: no account needed. A free account adds alerts whenever Letsencrypt changes state, plus 15 days of incident detail; Pro extends that to 90 days and Business to 13 months.
