Is it down right now?

What these numbers mean

Every service here is requested from multiple Fly.io regions on a schedule set per service — the most sought-after every 30 minutes from every region in the fleet, the rest less often and from fewer. Each page states its own cadence and how many regions its latest check ran from. A region only counts as down when it receives no usable HTTP response — if a site answers and refuses our client, that is a bot challenge, not an outage, and we label it as such rather than publishing a false zero.

A single failing region is treated as probe noise; a verdict only changes when two consecutive cycles agree. Where a vendor publishes an official status feed we read that too, and let it correct us in both directions.
