When Does Your Website Stop Working?

Two dates can take your site and email offline. Check both in seconds, then let us watch them for you, free.

Passive checks of public certificate and registration data. Nothing stored unless you ask for alerts.

The two expiry dates that take businesses offline

Every website has two clocks ticking. The HTTPS certificate usually renews every 90 days; when the automation quietly breaks, nobody notices until the day visitors see a full-page browser security warning. The domain registration renews yearly or less often; when it lapses, the website and every email address on the domain stop working at once, and the name itself can be picked up by squatters. Both failures are entirely preventable and both happen to real businesses constantly, usually because the renewal reminder went to an old inbox.

This tool checks both dates instantly, and if you like, watches them for you: alerts at 30, 14, 7, 3 and 1 day(s) before either expires. Our own hosting clients never need this (renewals are automated and monitored as part of hosting and care); the free monitor is for everyone else.

Frequently asked questions

How often do SSL certificates expire?

Most modern certificates are issued for 90 days and renew automatically. That automation is exactly what fails silently: a changed DNS record, an expired API key or a moved website breaks renewal, and the certificate runs out its remaining days without anyone noticing.

What actually happens when a certificate expires?

Browsers show a full-page security warning that most visitors will not click through, so the site is effectively down. Email sending from the website, payment integrations and APIs that call the site typically fail at the same time.

What happens if a domain registration lapses?

The website goes down and all email on the domain stops, usually after a short grace period. Beyond the grace and redemption periods the name returns to the open market, where drop-catchers register valuable domains within seconds.

Is the monitoring really free? What is the catch?

Free for up to five domains per email address, and the alerts contain no marketing. The honest business model: if an alert arrives at a bad time, our reply-to is right there and we will happily handle the renewal for you as paid work.

How do I stop the alerts?

Every email contains a one-click unsubscribe link for that domain. No account, no login, nothing to cancel.
