RealUptime Outages vs IsDown

IsDown aggregates official vendor status pages and layers crowdsourced user reports on top, which is how it catches incidents vendors never officially posted: its own blog attributes those early detections to user reports arriving from multiple countries. That is real signal, and this page credits it. RealUptime Outages adds the piece neither source can supply: first-party probes measuring every tracked service directly, with per-region readings and a published methodology.

The short version

IsDown catches what vendors will not admit, using other people's reports; RealUptime Outages measures the services itself and shows the readings.

IsDown's sharpest idea is one we agree with: vendor status pages under-report, and someone should say so. Its monthly recaps of incidents vendors never posted are a genuinely useful public service. The difference is mechanism. IsDown detects those incidents through reports about the vendor: other people noticing, in enough places, that something broke. RealUptime Outages detects them by measuring: our own probes hit every tracked service from four regions, the per-region readings are published next to any user reports rather than blended with them, and the thresholds that turn a failed probe into an outage call are documented in full. If your team wants vendor incidents piped into PagerDuty or Datadog, IsDown's integrations are ahead of ours today. If you want an outage call you can trace back to a measurement, free and without ads, that is what we built.

Independent probing of tracked services

Have

our own probes check every catalog service from four regions on a 60-second-to-30-minute cadence

Don’t have

combines vendor status pages with crowdsourced user reports; no first-party synthetic probing is described in its public material

Catches incidents vendors never posted

Have

a probe failure flags an outage whether or not the vendor acknowledges it

Have

its headline strength: user-report spikes surface incidents before, or without, vendor acknowledgement, per its own monthly recaps

Published detection methodology

Have

the full method, thresholds included, is public at /outages/methodology

Not published

how user reports are collected, verified, and thresholded is not documented on the pages we could access

Per-region measured readings

Have

each outage page shows what every probe region measured

Don’t have

no per-region measurement data; the signal is reports plus vendor pages

Free access to outage data

Have

every outage page is public, free, and unmetered; no ads or trackers

Partial

paid plans from $22 a month (annual) with a 14-day trial; no permanent free tier, per its pricing page

Incident-tooling integrations

Partial

public pages and feeds today; not a vendor-incident pipeline for your on-call stack

Have

API access on all plans plus Datadog, PagerDuty, Slack, and Teams integrations
