IsDown alternative

The IsDown alternative with real probes and a native app

IsDown aggregates the official status pages of thousands of providers and alerts you when they post an incident. Latency does that, then goes further: it probes the real endpoints from multiple regions and reconciles them against the official page, so you hear about an outage even when the provider has not posted one yet.
