Questions

Is Cos down, or is it just me?

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

How often do we check?

The status page every 15 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 Cos status page. HonkWatch also checks websites from 34 cities.
