Why monitor your website (and what it costs you when you don't)

An e-shop outage, or an expired SSL or domain, can cost more than a full year of monitoring. A calculation of what downtime really costs you.

The real cost of downtime

Take a typical online store:

Monthly revenue: 50,000 €
Working days per month: 22
Peak hours (10:00-14:00 + 18:00-21:00) account for roughly 60% of daily revenue
One peak hour ≈ 195 € in revenue

A one-hour outage on Friday at 12:00 = ~195 € in lost revenue. On top of that, add:

Lost customer trust (impact on their value over time, customer lifetime value)
An SEO penalty if Googlebot repeatedly hits a 5xx error (indexing issues, a temporary drop in ranking)
The cost of the IT person handling the incident

The worst case: SSL or domain

When an SSL certificate expires, Chrome shows the message "Your connection is not private". Visitors click "Back" and conversion drops to zero for everyone until you renew the certificate. And this can easily happen over the weekend, when nobody is watching.

When a domain expires (you forgot to renew the registration), the entire DNS zone for your domain stops working. Email, website and status page - everything. On top of that, recovery takes hours to days while DNS changes propagate.

What prevention costs

Professional uptime monitoring together with SSL and domain tracking starts at 4 € per month (Standard 4 €, Pro 9 €, Business 27 €). That is the equivalent of one lost hour of revenue over the whole year.

ePulz.io specifically:

Checks from 1 to 5 minutes depending on the plan, from multiple regions
Alerts 30, 14, 7, 3 and 1 day before SSL and domain expiry (WHOIS for .sk, .cz, .eu, .com and other TLDs)
Email + Telegram + webhook (Slack, Discord, Microsoft Teams via webhook)
A public status page for your customers

Conclusion

Website monitoring is not just a nice-to-have. It is buying insurance for a fraction of the cost of the potential damage. If your website brings in revenue or business contacts (B2B leads) above 5,000 € a month, there is no sensible reason not to have it.

Who finds out first: you or your customer?

Without monitoring, the path to discovering an outage is almost always the worst one. A customer hits a broken page, gives up, and maybe an hour later emails support. By the time the message reaches the right person, you have lost an hour of revenue and a chunk of trust. Monitoring flips this around: the first one to know is you, within a minute or two, before most visitors even notice. The whole value of monitoring lies in compressing the gap between "it broke" and "we know about it".

It's not just the homepage

"The site is up" is a headline, but a healthy homepage can sit in front of a broken business. Things worth watching separately: - The checkout / payment flow, where a broken step costs money directly. - The login flow, which depends on session storage and the database that the homepage may never even touch. - The API your mobile app or integrations depend on - unavailable to them, invisible to a browser test. - SSL and domain expiry, two failures that take everything down at once. - Background jobs (backups, billing), which have no page to load. Serious monitoring covers more than a single ping. ePulz.io offers twelve monitor types, so you tailor the check to the failure mode - HTTP/HTTPS with keyword and response-time checks, TCP port check, ICMP ping test, SSL and domain expiry, DNS, heartbeat for cron jobs, visual check, browser monitoring and three types via a LAN agent.

Why one check is not enough

If your monitoring is one server in one place, a blip on its network looks exactly like your website being down, and at three in the morning you get a false alarm. ePulz.io runs checks from three EU probes and declares an outage only when at least two out of three agree (2-of-3 consensus). A blip seen by one probe is ignored; a real outage seen by two or three triggers an alert. This is the difference between monitoring you trust and monitoring you eventually mute. Check frequency follows the plan: every 5 minutes on entry tiers, every 2 minutes on Pro and every 1 minute on Business. A shorter interval means a shorter window between failure and alert, which is the whole point for a revenue-critical service.

A status page pays for itself in saved tickets

When something really does break, a public status page is the cheapest support tool you have. Instead of fielding fifty "is it just me?" emails, you send everyone to one URL that already says "we know, we're working on it, ETA 20 minutes". It also signals competence: customers forgive a communicated outage far more readily than silence.

Get the alert where you'll actually see it

An alert nobody reads is the same as no monitoring. Email is fine for a daily summary, but an outage at three in the morning buried in an inbox you open at nine is useless. The right channel depends on severity and team habits: - Telegram / Slack / Discord / Microsoft Teams - instant, on your phone, hard to miss. Best for "the site is down right now". - Webhook - pushes the alert into your own on-call tooling or a chatbot, so you can route it, escalate it or open a ticket automatically. - Email - good for non-urgent things: SSL expires in 14 days, a weekly uptime report. A practical rule: send urgent alerts to a channel that makes the phone ring, and route noisy low-priority signals somewhere quieter, so the important ones never get drowned out.

The cost of a noisy monitor

There is a failure mode worse than no monitoring: a monitor that cries wolf. If you get three false alarms a week from one flaky probe, within a month the whole team mutes the channel, and the one real outage arrives to a silent room. That is why cross-region consensus matters more than check frequency itself. A monitor you trust at two in the morning is worth more than one that pings every ten seconds and is wrong half the time. Suppressing false alarms is not a pleasant bonus; it is what keeps the system trustworthy enough to act on.

When is it worth it?

A rough rule of thumb to decide:

Your situation	Monitoring priority
Hobby blog, no revenue	Nice bonus
Lead-generation site, the goal is a form	Worth it - a dead form silently costs leads
E-shop or SaaS with paying users	Essential - downtime is directly lost revenue
You run an API others depend on	Critical - your outage cascades into theirs

The break-even point is low. If a site brings in revenue or leads above a few thousand euros a month, the monthly cost of monitoring is a rounding error against a single hour of preventable downtime.

A note on where your data lives

If you operate in the EU, it is worth checking where your monitoring provider stores logs and which jurisdiction governs them. Monitoring data is metadata about your infrastructure - endpoints, response times, outage history - and keeping it within the EU simplifies your compliance story. ePulz.io runs its probes inside the EU precisely so that this is a non-issue for European customers.
