FAQ

Fast responses
to your questions

Still curious? Our team replies in under an hour, every day of the week.

How quickly will I be notified of an outage?
On Pro and Business, monitors are checked every 30 seconds and failures are confirmed from a second region before alerting — so you're typically notified within 30–60 seconds of a genuine outage, with no false alarms.
Do I need to install anything?
No. Domain Health Monitor is fully agentless — just paste a URL or hostname and we monitor it from our global probe network. There's nothing to install on your servers.
Can Domain Health Monitor track SSL and domain expiry?
Yes. We validate the full certificate chain daily and watch domain (WHOIS) expiry, alerting you 30, 14 and 3 days ahead so renewals never slip through the cracks.
Which alert channels are supported?
Email, Slack, Microsoft Teams, SMS, phone call, PagerDuty, Opsgenie, Jira and custom webhooks. Build escalation policies so the right person is paged at the right time.
