Website uptime monitoring

Know the moment your website goes down — and have the proof to fix it fast.

AmIUp checks your website every 5 minutes and sends you an email the moment something goes wrong. You'll know before your customers do — with a timestamp your hosting company can't argue with.

  • Website checks every 5 minutes with instant email alerts.
  • Security certificate (SSL) warnings before your site shows browser errors.
  • Domain expiration alerts so your site never goes offline because of a lapsed renewal.
  • Full outage history with timestamps, ready to share with your hosting company.

We monitor your website URL — not individual pages or checkout flows.

Everything AmIUp checks for your website

All the signals that matter to your business — in one simple view you don't need an IT background to understand.

Start monitoring

Is your website up?

AmIUp checks every 5 minutes and alerts you the moment your site stops responding, so you find out before your customers do.

Is your website slow?

AmIUp tracks how long your site takes to respond. A slow site loses visitors — we help you catch the slowdown before it costs you.

Is your website redirecting somewhere unexpected?

If your website suddenly sends visitors to a different page or domain, AmIUp flags it so you can investigate before it hurts your reputation.

Is your security certificate about to expire?

When a security certificate expires, browsers show a warning that scares customers away. AmIUp alerts you weeks before it becomes a problem.

Is your domain name about to expire?

A lapsed domain name takes your entire website offline instantly. AmIUp tracks your expiration date and alerts you before it becomes an emergency.

Proof for your hosting company

Every outage is logged with a start time, end time, and duration. When your host says "we didn't see anything," you'll have the record to prove otherwise.

SSL + domain health

Don't let an expired certificate or domain name take you offline.

Security certificates and domain names expire on a schedule — and when they do, your website can go down instantly, often without warning. AmIUp tracks both and alerts you before they become a problem.

  • Security certificate warnings weeks before expiration.
  • Domain name expiration alerts with registrar details.
  • Hosting provider visibility in one place.

IntegriCheck

We also watch for signs your website has been quietly altered.

Going "down" isn’t the only way a website can hurt your business. IntegriCheck watches for unexpected changes — like your site suddenly redirecting visitors to another page, or loading scripts that weren’t there before. If something changes, you’ll know.

This is what separates AmIUp from a free ping tool.

What we watch for
  • Unexpected redirects to other sites or pages
  • Unusual scripts loading on your website
  • Unexpected changes to how your site responds
