Questions

Is Let's Encrypt down, or is it just me?

The Let's Encrypt status page reports no problem. If it isn't working for you, the cause is more likely near you: your network, your browser, or a problem only in your area. Try another network or device.

How do we know?

We read the official Let's Encrypt status page. We don't guess from social media posts or reports.

How often do we check?

The status page every 2.5 minutes, day and night. We keep 90 days of history: a day we have no reading for shows as "no data yet", never as working.

Official status from the Let's Encrypt status page. HonkWatch also checks websites from 24 cities.
