<b>Q: I got a downtime alert but the site was fine the whole time. What happened?</b>
A: Most likely a single monitoring node hit a transient network blip between it and your server, not an actual outage. One node, one bad route, one false alarm.
The standard cure is confirmation from multiple locations: only declare "down" when 2+ geographically separate nodes fail within the same window. Good tools call this multi-location confirmation, and turning it on kills the majority of these.
Watch for the natural follow-up: if it keeps happening from the same node, the node may be sitting on an IP your firewall or WAF is rate-limiting. Whitelist your monitor's published IP ranges so it isn't being throttled like a scraper. That single fix removes a surprising share of phantom alerts.
