Is your server really up?
Check from 5 continents.
Real-time uptime monitoring from a global network of servers. Catch outages before your customers do, wherever they happen and whichever check type you run.
From signup to first global check in minutes
Add what to monitor
Paste a URL, hostname, IP address, or port. HTTP, ICMP or TCP: pick the right monitor type for what you're watching.
We check from 5 continents
Every monitor runs against our global network of monitoring locations, on intervals from one minute up to hourly.
You get alerted as soon as it's confirmed
Once enough locations agree the check is failing, you get notified by email, SMS, voice call, or Telegram. Escalation rules step through your contact methods until the alert is confirmed. Failures trigger a Forensic Snapshot (MTR route trace, DNS, response headers on HTTP checks, the served certificate on HTTPS), stored with the check next to the last healthy baseline to diff against.
Every layer, one dashboard
Real services depend on more than HTTP: ports, certificates, DNS resolution, ICMP reachability. Emercom monitors HTTP, ports and ICMP from the same global network, checks certificates on every HTTPS run, and captures DNS and MTR route diagnostics when something fails, all on the same dashboard, with the same alert rules.
HTTP & HTTPS
Status codes, response time, redirect chains, content matching, and SSL certificate health on every check.
ICMP (Ping)
Round-trip latency and packet loss from each location you monitor from. Catch routing changes and ISP issues before users do.
TCP Ports
Verify port accessibility and firewall rules across regions. Useful for SSH, SMTP, custom services, and game servers.
DNS Diagnostics
Failures capture a DNS query alongside an MTR route trace, so you can tell a resolution problem from a routing one. Query A, AAAA, CNAME, MX and TXT records on demand from resolvers worldwide with the free DNS tool.
SSL & TLS Certificates
Included on every HTTPS monitor, checked on each run. Detect expiry weeks ahead, and catch chain issues and hostname mismatches before they take you down.
Alert Routing & Escalation
Email, SMS, voice calls, Telegram. Escalation through up to ten levels, with acknowledgement and recovery notices.
We capture the evidence before an outage clears.
Every engineer has lived this: the pager goes off, you SSH in, and the symptom is already gone. Routes re-converged. The DNS cache rolled over. The cert that broke the chain rotated. You spend the next forty minutes trying to reproduce an outage that healed before you opened your laptop.
Emercom doesn't let outages cover their tracks. Every two hours, while your service is healthy, we capture a full diagnostic Forensic Snapshot from a monitoring node: DNS, MTR route trace, response headers on HTTP monitors, and the served certificate on HTTPS. When a check fails, we capture it again automatically.
By the time you open the dashboard, the broken state and the last known-good baseline are sitting side by side. Instead of reproducing the outage you compare two snapshots, and the cause is usually visible: a route that vanished four hops in, a cert that rotated to an incomplete chain, an A record pointing somewhere new.
Why multi-region monitoring matters
A site can be fast in New York and broken in Tokyo. CDN edges fail unevenly, DNS propagates at different speeds in different regions, ISP routing changes black-hole traffic from specific countries, and geo-firewall rules silently block users you didn't know about. Single-location uptime tools miss all of it.
Emercom runs your monitors across the regions you select. When something goes wrong, you see where it broke. The result tells you immediately whether you're looking at a global outage, a regional CDN failure, an ISP routing problem, or a misconfigured firewall.
Our nodes are spread across 5 continents and 13 countries. Latency from any monitored target to its nearest Emercom node is typically <50ms, so checks reflect real network conditions rather than transcontinental round-trips.
Status pages with subscriber notifications
Group your services into one status page: categories of services, your domain, your timezone. When something goes down, your subscribers hear about it on whatever channel they picked: email, SMS, Telegram, or a phone call.
Subscribers can sign up for a single service or for everything you publish, and unsubscribe with one click. You stay in control of what gets posted with an optional approval workflow.
Frequently asked questions
What teams ask before they get started. Anything missing? Drop us a line.
Do I need a credit card to start?
No. Get started without payment information. You can monitor sites, servers, APIs, ports, and SSL certs right away. Emercom is free for everyone until August 15, 2026, with full access to all features. Some features (like running status pages) are metered by credits, and your account starts with a small allowance. No card, no commitment.
What can I monitor?
Anything reachable on the public internet: websites, REST APIs, web services, SSH/SMTP/database ports, SSL certificates, custom application health endpoints. If it has a URL, hostname, IP, or port, Emercom can watch it.
How fast are alerts?
Alerts go out within seconds of a confirmed failure. How quickly a failure is spotted depends on your check interval, which you can set from every minute up to hourly. Confirmation comes from agreement across locations: a resource is only marked down when more than two monitoring nodes fail to reach it (or all attempted nodes, when fewer than three were tried), so a single-location flake never pages you. From there the alert routes through your preferred channels with optional escalation rules.
Do I get diagnostics with my alert, or do I have to dig for them?
No digging. Every monitor captures a Forensic Snapshot every two hours while healthy, and another automatically when a check fails. Open the failed check and the diagnostics from the failure sit right there, next to the most recent healthy baseline. No SSH, no racing the route to heal.
Where do checks run from?
A global network of monitoring locations. Checks run across the locations you select, and a target is only marked down once enough of them agree, so you see regional differences instead of one node's opinion.
