What is uptime monitoring?
Uptime monitoring is the continuous, automated checking of whether your website or server is reachable and responding correctly. A monitoring service sends regular requests to your address and records whether the response arrives, how fast it is and whether the content is what you expect. When something breaks, you get an alert instead of finding out from an angry customer.
Downtime is expensive. A site that is unreachable loses visitors, sales and trust, and an expired SSL certificate or a DNS change can take a service offline without anyone touching the server. Website monitoring catches these problems early, often before your users even notice.
The point of uptime monitoring is not just to measure a percentage. It is to shorten the time between a failure and your response. The faster you know, the faster you fix it, and the smaller the impact.
How ePulz.io monitors your website
ePulz.io runs your checks from multiple locations and confirms every incident before it bothers you, so a single network hiccup does not turn into a false alarm at three in the morning.
Three EU probes with 2-of-3 consensus
Every check runs from three independent probes inside the European Union. An outage is only declared when at least two of the three probes agree that your site is down. This consensus model filters out transient routing glitches and one-off timeouts, so the alerts you receive are real.
Check intervals from 1 minute
Depending on your plan, ePulz.io checks your monitors every 5, 5, 2 or 1 minute. Shorter intervals mean you learn about server uptime problems sooner. Across all plans the underlying engine, probe network and consensus logic stay the same.
Monitor types
ePulz.io is more than just a simple ping. It offers twelve types of monitors so you can track every layer that keeps your service online:
- HTTP / HTTPS monitoring - checks that your website responds with the right status code and content, and measures response time.
- SSL monitoring - watches your TLS certificate and warns you well before it expires, so HTTPS never breaks unexpectedly.
- Domain (WHOIS) monitoring - tracks your domain registration and alerts you before the domain itself is about to expire.
- TCP port monitoring - verifies that a specific port and service (database, mail, custom app) is open and accepting connections.
- DNS monitoring - checks that your DNS records resolve to the expected values and catches unwanted or accidental changes.
- Ping (ICMP) monitoring - confirms that a host is reachable on the network at the lowest level.
- Heartbeat monitoring - watches cron jobs and background tasks: if the expected signal does not arrive in time, you get alerted.
- Visual monitoring - takes screenshots and detects visual changes, so you notice when a page renders broken even with a 200 status.
- LAN agent monitoring - a lightweight Linux agent monitors internal services on your own network that are not reachable from the public internet.
Instant alerts the way you work
When a confirmed incident happens, ePulz.io notifies you through the channels you actually use: email, Telegram, webhooks, Slack and Microsoft Teams. You can route different monitors to different channels and silence noise with quiet hours.
Beyond alerts, ePulz.io gives you public status pages to keep your users informed and SLA reports to prove your availability over time.
Why EU hosting and GDPR matter
ePulz.io is built and hosted in the European Union. Your monitoring data stays within the EU, which keeps you on the right side of GDPR without extra paperwork or transatlantic data transfers.
For EU businesses this is not a detail. It is a compliance requirement and a trust signal you can pass on to your own customers.
Why not just ping?
A plain ping only tells you a server answers on the network. It says nothing about whether your website actually loads, whether the SSL certificate is valid, whether DNS resolves correctly or whether the page renders without errors.
Real website monitoring checks the whole chain, from DNS and TLS to HTTP responses and visual rendering. That is the difference between knowing a box is powered on and knowing your customers can use your service.
