Features / Domain expiry
Domain expiry monitoring
An expired domain takes down your site, your email and your customers’ trust at once. Halvyn checks your registration date at the registry and warns you well before it lapses.
What Halvyn checks
- Registration expiry from the authoritative registry via RDAP, the IANA-standard successor to WHOIS
- A warning window you choose, in days
- SSL certificate expiry is covered by website monitors on the same account
Common uses
- Primary product and marketing domains
- Defensive and country-code domains
- Client domains agencies look after
Included with every monitor
One incident per outage
Repeated failures roll into a single incident with a timeline, instead of a flood of duplicate alerts.
Blip recheck
A failed check is re-run within the same cycle before it counts, and an incident opens only after consecutive failures — a single network blip never pages anyone.
Escalation until acknowledged
Email, Slack, Microsoft Teams, Discord, Google Chat, webhooks, SMS, voice calls and on-call rotations — with one-click acknowledge links in every alert.
Incident management
Investigating → identified → monitoring → resolved states, assignees, comments, SLA timers per severity and postmortems.
Public status pages
Uptime bars, live incidents and manual updates on a page you can put on your own domain.
Maintenance windows
Checks keep running during planned work but alerts stay quiet, so your history stays complete.
SLOs and monthly SLA reports
Track objectives per monitor and email an uptime report to owners every month.
Flat pricing
Every check type on every paid plan, one price per plan — no per-host, per-check or per-feature metering.
