summary: Live checks
description: Whether the site answers now, and how it has answered. Every five minutes the Worker requests a fund page, the API index and an MCP handshake through the public address, and reads the nightly report. This file gives each check's state, its share of passed checks over 24 hours, 7, 30 and 90 days, 90 days of daily figures, the incidents and the deployments. It is computed when asked and kept one minute at the edge. The checks run on Cloudflare, like the site. An outage of Cloudflare itself stops them too, so it shows as slots with no data, which are never counted as up.

method: Every five minutes the Worker requests a fund page, the API index and an MCP initialize through the public address, and reads status.json to see whether the nightly build ran. A slot with no check, for example during a Cloudflare incident, counts as no data, never as up, and is left out of the percentages.
