Is your server really up?
Check from every continent.
Real-time uptime monitoring from a global network of servers. Catch outages before your customers do — across every region, every check type, every minute.
From signup to first alert in under a minute
Add what to monitor
Paste a URL, hostname, IP address, or port. HTTP, ICMP, TCP, DNS, or SSL — pick the right check type for what you’re watching.
We check from every continent
Every monitor runs in parallel from our global network of locations across North America, Europe, Asia, and the Pacific — on intervals as short as one minute.
You get alerted instantly
The moment a check fails, you get notified by email, SMS, voice call, or Telegram. Smart escalation rules route critical alerts to on-call.
Every check type, one dashboard
Most uptime tools watch HTTP and call it a day. Real services depend on more than that — ports, certificates, DNS resolution, ICMP reachability. Emercom monitors all of it from the same global network, 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, jitter, and packet loss from every region. 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 Resolution
Track A, AAAA, CNAME, MX, and TXT records from resolvers worldwide. Spot propagation lag and zone issues fast.
SSL & TLS Certificates
Detect expiry weeks ahead. Catch chain issues, hostname mismatches, and revoked certs before they take you down.
Smart Alert Routing
Email, SMS, voice calls, Telegram. Escalation rules, alert windows, and on-call rotation — without alert fatigue.
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 watches every monitor from every region at the same time. When something goes wrong, you see where — not just that. 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 distributed across North America, Europe, Asia, and the Pacific. Latency from any monitored target to its nearest Emercom node is typically under 50 ms, so checks reflect real network conditions rather than transcontinental round-trips.
Status pages with subscriber notifications
Group your services into one branded status page — categories of services, your logo, 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 start a trial. Anything missing? Drop us a line.
Do I need a credit card to start the free trial?
No. Start your trial without payment information — you can monitor sites, servers, APIs, ports, and SSL certs right away. Some features (like running status pages) are metered by credits, and your account starts with a small allowance so you can try them out. Cancel anytime, no questions, no charge.
What can I monitor?
Anything reachable on the public internet: websites, REST APIs, GraphQL endpoints, web services, SSH/SMTP/database ports, DNS records, 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. We require a configurable number of consecutive failed checks before alerting (default: 2) to filter out transient blips, then route the alert through your preferred channels with optional escalation rules.
Where do checks run from?
A global network of monitoring locations across North America, Europe, Asia, and the Pacific. Every monitor runs from every location in parallel, so you see regional differences immediately.
