All three probes, on three continents, have to agree before anyone gets paged. Single-region flaps are logged, not escalated. Status pages and on-call included.
Real probes in Amsterdam, Virginia and Singapore. Or skip it and start free.
25 monitors free forever, commercial use included. New accounts start on a 14-day Team trial — no card required.
Not a mock-up. These are the rows our production engine wrote, on one of our own monitors. See the working →
Counted live from production, including our own test workspaces — which is why the numbers aren't round. See the working.
Most tools page on the first failed check. That is why your phone has gone off for a datacenter that fixed itself in forty seconds. We wait until the failure is real.
Logged as an anomaly with the full decision trail. Visible in your dashboard tomorrow morning. Nobody is woken.
Three probes, three continents, inside thirty seconds. Mercury has already written the first investigation. Now it's worth waking for.
And when the cause is an upstream provider having a bad day, we tag it instead of blaming you — we mirror 14 status pages to check.
No. 25 monitors, forever, commercial use included. New accounts also get 14 days of the Team plan to feel the difference — no card. When it ends, checks slow to every 3 minutes and nothing switches off.
We watch ourselves with Repose and the status page is public. If one of our probe regions fails, the consensus bar drops to the regions still reporting and every decision says so — our outage must never hide yours.
Then you already know what a 3am false alarm costs. Point Repose at the same endpoints for a fortnight and compare what each one woke you for. That comparison is the whole pitch.
Consensus is per-monitor. Set it to 1 and we behave like everyone else. The default is 3 because that's what the evidence supports — but it's your call, per service.
No card. Commercial use fine. We'll only wake you when all three probes, on three continents, agree — and Mercury will already know why.
