Questions

Is Hmhco down, or is it just me?

The Hmhco 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 Hmhco status page. We don't guess from social media posts or reports.

How often do we check?

The status page every 7.5 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 Hmhco status page. HonkWatch also checks websites from 34 cities.
