How it works

The same outage at 2am - with our uptime monitoring tool and without it

Your site can have issues and go down while you sleep. The only thing that matters is how long it takes you to find out that your site is not available.

Without website uptime monitoring
02:14 Your site unexpectedly goes down and nobody notices it.
02:05 You're asleep but pages are not available for visitors. They leave for a competitor.
08:38 You wake up guessing: why are there no orders?
09:05 Find an angry message from your customer: "Your site's been broken all night."
09:28 Site is fixed after 7 hours of downtime - lost sales and trust.

Why HostTracker

Website monitoring that goes deeper than a homepage ping

A simple availability checker only tests whether your pages or a homepage responds. HostTracker website uptime monitoring service monitors the sections that can actually affect your business - pages, ports, APIs, transactions, SSL certificates, server, domains, blacklist status and response time.

300+ checkpoints, one confirmed verdict

Most checkers often perform tests from only one place. Host-Tracker site uptime monitor can verify outages from multiple global checkpoints, so a temporary network issue or bad route does not trigger a false alarm.

Seen like a real visitor - HostTracker can open pages, check content, test key flows, not just perform server uptime monitoring.
Confirmed from several locations before alerting - we make fewer false alarms.
Website uptime monitoring dashboard - you see what broke and where: error details, affected checkpoints, incident time, duration.
Audit-ready history of uptime and response time, whenever you need the proof.

Uptime monitoring service that fits any business

Whatever your site does for you, there's a version of "it went down at the worst possible moment". Here's how our advanced uptime monitor saves you from yours.

Monitoring for E-Commerce

"I sell things online"

Every minute your site is down is an order you'll never get.

We watch your shop and can even click through your checkout - so you hear about a broken "Buy" button before your customers can notice it.

Monitoring for Banks & Fintech

"I run a bank or fintech"

If online banking is down - customers definitely panic and regulators ask why.

Independent monitoring checks from 300+ locations, login & payment scenarios, instant escalation and audit-ready site uptime history. Trusted by banks including OTP Bank.

Monitoring for Agencies & Studios

"I look after clients' sites"

A client shouldn't be the one to tell you the site is down.

Watch uptime monitoring for the client's site from one dashboard, with a full monthly report you can hand over - and look like the pro.

Monitoring for Hosting Providers

"I host other people's sites"

Your customers choose you by your uptime and availability.

Frequently asked questions.

You can monitor site uptime instantly and for free using our checker at the top of this page or our dedicated domain uptime checker. Just enter your domain URL and Host Tracker tests it in real time from multiple locations worldwide. All checks run from several countries at once and you can see whether the site is down for everyone or it has issues only in certain regions. For ongoing coverage, set up 24/7 domain uptime monitoring and we will alert you automatically the moment it goes down.
Website uptime monitor means a service that automatically checks your website (homepage, certain page or domain) at regular intervals - every minute, second etc. - and alerts you the moment it becomes unavailable. Host Tracker can run these checks from 300+ checkpoints worldwide.
Reasons could be different. Common causes include server overload, DNS failure, bad code deployment or just hosting provider issues. HostTracker can find the exact error and which locations are affected. It helps you to narrow down the issue immediately instead of guessing.
Commonly, for most sites, every 1–5 minutes is normal. For example, business sites that are very critical for downtime benefit from 1-minute checks; a personal blog can use a monitor frequency of 5 minutes. The free uptime monitoring plan checks every 30 minutes; paid plans go down to 1 minute.
HostTracker can notify you in different ways: SMS, email, voice call, Telegram, Slack, Viber, Discord, web push or webhook. You can also combine different channels and set escalation rules. For example, send a Telegram message first, then a phone call if the site is still down after 5 minutes. Rules can be very flexible.
We make several rechecks of your site from several different locations before alerting you. If only one location sees a problem and others are fine, it won't wake you up at 3am - it logs this situation and keeps watching. You get alerted when multiple locations confirm the issue.
If it happened once for a short time - it has minimal direct impact. Frequent or prolonged downtime hurts your SEO or can lower your rank positions. When Googlebot repeatedly cannot reach your site it may lower your crawl frequency too. Catching issues early with HostTracker uptime monitoring tools helps to keep your uptime at 99.999% and your SEO unaffected.
The HostTracker monitoring tool supports 13 monitoring types: website HTTP/S availability, Ping (ICMP), TCP port, transaction checks (click-through login and checkout flows), web content checks, API monitoring, page speed, database checks, server load, Web Risk (Google Safe Browsing), Blacklist/DNSBL and domain & SSL certificate expiry.
Most simple availability checkers ping your homepage from one location and send an email only. Host Tracker confirms all outages from 300+ locations worldwide before alerting you. It monitors 13 different check types beyond just HTTP. It can reach you on 9 alert channels including phone calls and has been trusted by 500,000+ websites since 2004.
We have a free trial and a free plan. Host-Tracker provides a 30-day free trial with full access to all features and no credit card required for this. After the trial period you can pick a paid plan or stay on the free plan. The free plan includes basic web uptime monitoring features with no time limit.
