How verification works

Most false alarms are one region having a bad second.

A single monitoring server sees a dropped packet, a slow TLS handshake, a momentary route flap — and pages you at 3am. Your service was fine the entire time. Do that a few times and your team starts ignoring alerts, which is worse than having none at all.

SteadyStack never alerts on one opinion.

Step 01 · BREADTH

Seven regions, every 60 seconds (paid tiers)

Every monitor is checked from all seven (or 3 primary regions on the free tier): Western and Eastern North America, Western and Eastern Europe, and three Asia-Pacific regions covering Japan and Korea, Southeast Asia, and wider APAC. Not a rotation — all regions, every cycle.

Step 02 · VERIFY

A failure triggers an immediate re-check

Before a failure counts toward anything, the region that saw it checks again straight away. Single dropped packets and one-off TLS timeouts die here, silently, without ever reaching your phone.

Step 03 · CONFIRM

Four of seven must agree (paid tiers)

Only when four regions (2-of-3 on the free tier) independently confirm the failure do we open an incident. A region that's simply slow to respond is excluded from the count rather than counted as a failure — so one congested route can neither trigger an alert nor suppress one.

Step 04 · CLASSIFY

We tell you which kind of failure it is

Three regions failing while four succeed isn't an outage — it's regional degradation, usually a CDN edge or a geo-routing rule, and we label it that way. A majority failing is a global outage. Different problems deserve different alerts.

Real-World Quorum Logic

Worked verification examples

Worked example ANo alert sent
wnam FAILenam FAILweur FAILeeur OKapac OKapac-ne TIMEOUT (excluded)apac-se OK

→ 3 of 6 counted. Below quorum. No page sent. Logged as regional degradation, Americas + Western Europe.

Worked example BQuorum Met · Alert Paged
wnam FAILenam FAILweur FAILeeur FAILapac FAILapac-ne OKapac-se FAIL

→ 6 of 7 confirm. Quorum met. Incident opened, on-call paged, status page updated.

Where we don't check from — yet

We check from North America, Europe and Asia-Pacific (including Tokyo and Sydney). We do not currently have sovereign probes in South America, Africa, or the Middle East.

We'd rather tell you that than pad a number. If your users are concentrated in those regions, a global outage will still page you — but region-specific problems there may not surface, and you should know that before you rely on us. If your critical users are in those regions, pairing SteadyStack with a heartbeat or cron-job monitor for those endpoints will catch region-specific failures until our coverage expands. Our live coverage, including what's coming, is on the locations page.

Competitive Analysis

Why Engineering Teams Choose SteadyStack

Compare SteadyStack head-to-head against legacy uptime monitoring tools. Our core difference is the confirmation rule: four of seven independent global regions must agree before you are paged. Faster check intervals, broader edge coverage, and native synthetic testing are included - but the quorum model is what eliminates false positives at the source.

Note 1:Being straight with you: Checkly runs 22 locations to our 7, and Better Uptime's 3-of-4 quorum is a genuinely good design that solves the same problem we do. We think 4-of-7 across published, health-monitored regions is better — and unlike anyone else here, we publish enough detail for you to verify it yourself. Pingdom runs 100+ locations and still gets false-positive complaints, which is rather the point: the confirmation rule matters more than the count.

Frequently asked questions

Find immediate answers regarding SteadyStack's global network, subscription models, and telemetry configurations.

How fast are the checks performed, and are there interval limits per tier?
Verification checks execute natively at the edge. The check frequency depends on your subscription tier: the Initiate (Free) tier supports 3-minute standard check intervals (1-minute intervals for your first 10 monitors) with 2-of-3 quorum consensus across 3 primary edge regions, the Netrunner plan supports down to 30 seconds across all 7 sovereign regions with 4-of-7 quorum consensus, and the Construct (Enterprise) plan supports high-frequency telemetry checks down to 10 seconds. All checks are backed by an independent out-of-band Hetzner sentinel.
What is multi-region consensus verification, and how does it prevent false alerts?
Outages on the Internet are often localized due to routing anomalies or regional network drops. When a SteadyStack edge probe detects that your monitor is DOWN, it triggers an immediate local re-check and queries our other sovereign regions. SteadyStack requires 4 of 7 global regions to independently confirm the failure before opening an incident (2-of-3 on the free tier). This voting system isolates regional route flaps from true global outages.
How do private probes monitor internal infrastructure behind firewalls?
Our lightweight dockerized probes run internally on your own secure private subnets. Instead of requiring you to open incoming firewall ports or set up public DNS records, the private probe establishes a secure outbound WebSocket control channel to our edge Durable Objects. The probe securely polls jobs, executes them locally, and pushes metrics back to SteadyStack, ensuring zero inbound security risks.
What notification channels are supported for dispatches?
Alerts can be routed dynamically based on severity thresholds. We support instant dispatches to Slack, Discord webhooks, Microsoft Teams, and email. For team alerting rotation, the Construct plan integrates directly with pager services like PagerDuty or custom webhook endpoints to execute automated disaster recovery actions.
What are the exact capabilities and limits of the Initiate (Free) plan?
The Initiate plan is designed for side projects, indie developers, and commercial applications. Free plan includes commercial use permitted in writing with 50 active monitors (3-minute standard interval, 1-minute interval for your first 10 monitors), 3 primary edge regions with 2-of-3 quorum consensus, 1 public status page, and transparent probe telemetry. It requires no credit card and supports HTTP, SSL/TLS, DNS, and Heartbeat checks with 3 days of log retention.
Can I monitor protocols other than standard web pages?
Yes. SteadyStack supports comprehensive system checks including HTTP/HTTPS, SSL/TLS certificate handshakes, DNS records (A, MX, TXT, CAA), TCP port reachability, ICMP PING, and multi-step browser sequence simulations. Note that advanced protocols like TCP/Ping and browser sequences require upgrading to a paid tier (Netrunner or higher).
How does the SSL/TLS monitoring module work?
The SSL monitoring module proactively connects to your secure endpoints to verify the entire certificate chain. It checks the certificate authority trust, key strength compliance, subject alternative names (SANs), certificate transparency logs, and revocation status via OCSP stapling. You will receive warning alerts 30 days prior to expiration to prevent unexpected certificate lapses.
Can I customize the look of my public status pages?
Absolutely. SteadyStack supports custom themes, status grid layouts, and white-labeling. You can map public pages to your own custom domain, configure responsive grid widgets, and select themes (such as Matrix Green, Cyberpunk Pink, or Terminal Dark). Paid plans allow you to completely remove SteadyStack branding.
How secure is my telemetry data, and what is your log retention policy?
All client settings, credentials, and telemetry headers are encrypted at rest and in transit. Raw event logs and latency metrics are retained depending on your tier: 3 days for the Initiate tier, 30 days for the Netrunner tier, and up to 1 full year for the Construct tier. High-tier plans also support full automated data exports to external storage objects without vendor lock-in.
