Common Questions.
What does the Health Score mean?
The Health Score (0-100%) is a combined metric of Liveness (is the site up?), Performance (how fast does it redirect?), and Security (does it contain known threat patterns or high-risk top-level domains?).
How accurate is the latency test?
Our scanner measures the TTFB (Time to First Byte) and full redirect handshake from our global edge nodes, giving you a precise look at what your users will experience.
Why is my URL flagged as Suspicious?
A 'Suspicious' status often triggers for new or high-risk TLDs (like .zip or .top), high-entropy hostnames, or servers that explicitly block HEAD requests, which are common tactics for phishing sites.
What is the Guardian Health Monitor?
While this tool is an on-demand checker, our Guardian engine (available on Social+ plans) provides 24/7 background monitoring and automatic fallback routing if your destinations go down.
