Uptime, SSL and domainmonitoring that warns you first
Know when a website or service is down — and when a certificate or domain is about to run out — before your customers do. TBS Infrastructure checks from the internet, keeps uptime % and every outage with its duration, and watches your scheduled jobs too.
Outages, expiries and missed jobs — all in one place
A server can look healthy from the inside while customers cannot reach the website. TBS Infrastructure's own server in Europe checks your websites and ports from the internet every 1, 2, 5 or 10 minutes. Before it calls something down, it checks again after 30 seconds, so one slow answer does not wake anybody up.
Certificates and domain registrations are watched too — also for sites behind a CDN or at a hosting company — so an expiry never becomes an outage.
Website and port checks
HTTP(S) checks, optional keyword on the page, or a plain TCP port such as a mail or database port.
Uptime % and outages
Uptime per check and every outage with its start, end and duration — ready for your monthly report.
SSL certificate expiry
Warnings weeks before a certificate runs out, and an alert when a certificate is wrong for the name.
Domain expiry
Warnings before a domain registration runs out — the outage nobody expects.
Heartbeat for scheduled jobs
Your job calls a secret link when it ran (every 5 minutes up to once a week). No call in time, or a failure report, means an alert.
Status page and badge
Show customers your service status with uptime bars and incident notes — never server names or addresses.
Honest limits: checks run from one location (TBS Infrastructure's server in Europe). Checks from several countries and browser login-flow tests are not offered today.
Alerts without noise
Questions
How often are websites checked?
Every 1, 2, 5 or 10 minutes — you choose per check. A failed check is repeated after 30 seconds before the site counts as down.
Where are the checks run from?
From TBS Infrastructure's own server in Europe. Checks from several countries are not offered today.
What is a heartbeat check?
Your scheduled job (for example a nightly backup) calls a secret link when it ran. If the call does not come in time, or the job reports a failure, you get an alert.
Does it work for sites behind a CDN?
Yes. Certificate and domain-expiry checks also work for sites behind a CDN or at a hosting company.
Can I check my domain for free?
Yes. The free domain health check on our website needs no login.
