Questions

Is Duolingo down right now?

Checks are succeeding, user reports are near the baseline, and the vendor status page is clear.

How does Damn is it down decide Duolingo's status?

Three signals. Anonymous reports are compared with the usual volume for this hour. HTTP checks from Cloudflare have to fail twice in a row before we call our side down. When the vendor publishes a status JSON feed, that incident level is included too.

How often is Duolingo checked?

About every five minutes. The cron runs each minute and rotates through the catalog, so a full pass takes a few minutes.
