How to Prevent Domain Expiry Disasters With Automated Monitoring

It sounds impossible, but major companies let their domains expire regularly. Google forgot to renew google.com.ar. Microsoft let hotmail.co.uk lapse. Sorenson Communications — a Fortune 1000 company — lost their primary domain for days. If it can happen to them, it can happen to you.

What Happens When a Domain Expires

When your domain expires, the consequences cascade immediately:

• Your website becomes unreachable — DNS resolution fails completely
• Email stops working — MX records die with the domain
• API integrations break — any service calling your API gets DNS errors
• SSL certificates become useless — they are tied to the domain name
• After a grace period (usually 30-45 days), domain squatters can register your expired domain and demand ransom

Setting Up Domain Expiry Monitoring

In Monitorion, go to Monitors → New Monitor → Domain Expiry. Enter your domain name — that is it. Monitorion queries WHOIS data to check the expiry date and alerts you when it falls below your threshold.

The default alert threshold is 30 days before expiry. For critical domains, set it to 60 or 90 days — giving you plenty of time to renew even if your registrar has billing issues or your credit card expired.

What Monitorion Shows You

The domain expiry monitor displays:

• Days remaining — color-coded (green > 30 days, amber 7-30 days, red < 7 days)
• Exact expiry date — pulled from WHOIS data
• Registrar name — so you know where to go to renew

Best Practices

Monitor all your domains, not just your primary one. Most teams have a handful of domains — the primary site, marketing domains, short URLs, internal tool domains. Any one of them expiring can cause problems.

Enable auto-renewal at your registrar — but still monitor. Auto-renewal can fail if your payment method is expired, your registrar has technical issues, or domain transfer locks prevent renewal.

Combine with WHOIS Change monitoring. Monitorion also offers WHOIS Change detection — alerting you if registrar, nameserver, or status flags change. This catches unauthorized domain transfers before it is too late.

Domain monitoring costs nothing extra on the Free plan. Add your domains now — it takes 10 seconds each.
