Website Downtime

Roei Hazout

What if: You run a store, and one morning, customers show up; but the doors won’t open? No explanation, no warning, just a locked entrance and lost business. That’s exactly what happens when your site is down.

If someone tries to visit and your website doesn’t load, that’s website downtime. You lose traffic, sales, and sometimes even trust.

What Is Website Downtime?

Website downtime is any period when your website is unreachable to users. It could be a few seconds or several hours. Either way, people can’t access your site, and you’re likely losing something be it customers, leads, or credibility.

Sometimes it's full downtime (the whole site crashes). Other times, it’s partial, like your homepage works but the checkout page doesn’t.

Every second counts. That’s why learning how to check website uptime and catch downtime early is essential.

Why Does Site Downtime Happen?

Downtime isn’t always your fault, but it’s always your problem. Here’s what usually causes it:

  • Server issues: Hosting providers sometimes go offline for maintenance or crash due to overloads.
  • DNS problems: If your DNS settings break or don’t resolve properly, your site won’t load.
  • Expired domains or SSL certificates: If you forget to renew, your site may go offline or show scary warning messages.
  • Coding errors: One bad plugin, update, or line of code can crash an entire page.
  • DDoS attacks: These are intentional attacks that flood your server with fake traffic to knock it offline.
  • Network issues: Sometimes it’s not your site at all, but a network issue between the user and your host.

No matter what caused it, you need to know as soon as it happens. That’s where downtime monitoring comes in.

How to Check Website Uptime

If you’re wondering whether your site is down or if it’s just you, there are a few quick ways to check.

  1. Try loading your site from another device or network
    Use your phone’s data instead of Wi-Fi. Still down? That’s a sign.
  2. Use an online tool
    Sites like downforeveryoneorjustme.com or isitdownrightnow.com can check for you instantly.
  3. Use command line tools
    A quick ping yourdomain.com or curl command can tell you if your site is responding.

But these are manual checks. What you really want is a site down monitor watching your site 24/7.

What Is Downtime Monitoring?

Downtime monitoring is a system that regularly checks if your site is up and running. If it detects a problem, it alerts you, usually by email, text, or app notification.

You can set up downtime monitoring to check your website every minute (or even every few seconds), from multiple locations around the world.

If it fails a few checks in a row, it lets you know so you can act fast.

Good monitors can even track:

  • How long the site was down
  • What response code your server returned
  • Whether specific pages were affected

This kind of visibility helps you catch problems before your users do.

Types of Monitoring You Can Use

Not all monitors are the same. Here are a few types you’ll see:

  • HTTP checks
    Just checks if your site responds properly when loaded.
  • Ping monitoring
    Pings your server to make sure it’s reachable.
  • Port monitoring
    Checks if a specific service like email or FTP is online.
  • Transaction monitoring
    Follows a flow, like logging in or completing a checkout, to test if key features are working.

If you run an eCommerce site or SaaS tool, transaction monitoring is especially important as it tells you if part of your site is broken even if the rest is up.

What to Do When Your Site Is Down

Here’s what you should do, step by step, the second you get a downtime alert:

  1. Confirm it’s real - Use another device or uptime checker to rule out false alarms.
  2. Check your host’s status page - Many hosting services like Cloudflare, AWS, or Bluehost have real-time dashboards.
  3. Check domain and SSL expiration - Visit your site in a browser and see if there’s a certificate error or domain warning.
  4. Check server logs or error messages - These can often tell you exactly what broke.
  5. Disable recent changes - If you pushed an update or plugin right before the crash, roll it back.
  6. Contact your hosting support - If you’re stuck or suspect a server-wide issue, get their help.

And once it’s fixed, note the cause, record how long the downtime lasted, and learn from it.

How Much Downtime Is Too Much?

No site is perfect, but your goal should be 99.9% uptime or better. That gives you about 8.7 hours of downtime per year.

Here’s what different uptime percentages actually mean:

Uptime Max Downtime Per Month
99 % 7 hours 18 minutes
99.9 % 43 minutes
99.99 % 4 minutes

Even a few minutes can cost big money depending on your traffic. That’s why a site down monitor and a plan for quick recovery are essential.

Best Practices to Avoid Website Downtime

Here’s how you can reduce the chances of a crash:

  • Use a reliable hosting provider with strong uptime guarantees
  • Set up automatic renewal for domains and SSLs
  • Back up your site regularly, so recovery is fast
  • Use a content delivery network (CDN) to offload traffic
  • Test code and updates on a staging site before going live
  • Monitor uptime constantly with tools like UptimeRobot or Pingdom

The goal is not just to fix issues fast, but to prevent them in the first place.

Conclusion

Website downtime is lost traffic, lost money, and lost trust. Despite it being a small blog or a full-scale online store, your site being down is never good news.
