Domain Expiration Monitoring
One missed renewal is all it takes. A client's domain expires, their site goes dark, and their customers land on a parking page. Sentinel watches every domain you manage and makes sure that never happens.
How It Works
Automatic domain tracking for every monitor
When you add an uptime monitor for any website, Sentinel automatically queries the domain's WHOIS registration data and begins tracking its expiration date. There is nothing extra to configure. Every domain you monitor is covered from day one.
As the expiration date approaches, Sentinel sends multi-tier alerts at 30, 14, 7, and 1 day before expiry. Each threshold is configurable per monitor, so you can set tighter windows for critical client domains and wider windows for domains with auto-renewal enabled. All domain expiration dates are visible in a centralized dashboard that spans every team and every client site.
- WHOIS data queried automatically for every monitored domain
- Alert thresholds at 30, 14, 7, and 1 day before expiry
- Centralized view across all teams and client sites
Features
Everything you need to prevent domain lapses
Multi-Tier Alerts
Configurable alert thresholds at 30, 14, 7, and 1 day before expiration. Choose which intervals matter for each domain and never be caught off guard.
Centralized Dashboard
See every domain expiration date across all your client sites in a single view. Sort by urgency, filter by team, and export for client reporting.
Automatic Tracking
No extra setup required. Every uptime monitor automatically checks domain registration expiry alongside uptime, SSL, DNS, ping, TCP port and heartbeat/cron monitoring.
The Stakes Are High
Why domain monitoring matters
Domain expiration is one of the most preventable yet devastating failures in web operations. When a domain lapses, the consequences cascade quickly and the damage is often irreversible.
Client Trust Damage
When a client's domain expires on your watch, the conversation that follows is one no agency wants to have. Trust built over months of good work evaporates in a single incident. Clients expect their web presence to be managed, and a lapsed domain signals a fundamental failure in that responsibility.
SEO and Traffic Loss
Search engines deindex expired domains rapidly. Even a brief lapse can cause months of organic rankings to disappear. Backlinks built over years start returning errors. Recovering search visibility after a domain expiration often takes longer than the original SEO campaign that built those rankings.
Domain Squatting Risk
Automated bots continuously scan for expiring domains with established traffic and authority. Within hours of expiration, a valuable domain can be registered by a squatter who will either fill it with ads, use it for phishing, or demand a premium to sell it back. The legal process to recover a squatted domain is expensive, slow, and not guaranteed to succeed.
