How to Check If a Website Is Available (Without Guessing)

"Is it actually down, or is it just me?" is a more useful question than it sounds.

The answer changes what you do next. Here's how to actually find out, rather than guess.

Reload, but pay attention to the error

A simple reload tells you more than it seems to.

A timeout, a "server not found," and a certificate warning are three different problems. Note which one you're seeing before you do anything else.

Check from a connection you don't normally use

Switch from Wi-Fi to mobile data, or ask someone on a different network to try.

If it loads for them and not for you, the problem is very likely on your end — your ISP, your router, a DNS cache, or a VPN — not the website.

Check from a device you don't normally use

Your phone, a friend's laptop, anything other than the machine you were just using.

This rules out a browser cache issue or a local network quirk specific to one device.

Look at what actually loads

If the page partially loads — text but no images, or a blank page instead of an error — that's a different situation from a connection timing out entirely.

A partially broken page often points to the application itself, not the network path to it.

Separate "down" from "certificate warning"

A security warning in the browser doesn't necessarily mean the site is unreachable — it can mean the SSL certificate has a problem while the server itself is responding fine. Worth reading what actually happens when an SSL certificate expires if that's what you're seeing.

The limits of checking it yourself

All of the above works when you're already looking at the problem.

It doesn't help with the outage that happens at 3 a.m., or the one that starts five minutes after you close your laptop.

That's the actual gap automated uptime monitoring is meant to cover — something checks on a schedule so you don't have to be the one doing it.
