Website & Service Ping Tool
Measure live HTTP/HTTPS response times, DNS lookup speed, HTTP status codes, and server response headers from our monitoring servers.
Understanding Website Latency & Response Times
Web performance directly affects user retention and Google search rankings (Core Web Vitals). When you ping a website or API endpoint, total latency is composed of three sequential phases:
DNS Resolution
The time required to translate your domain name into an IP address via authoritative nameservers (typically 10-50ms).
TCP & TLS Handshake
Establishing the socket connection and negotiating cryptographic keys for TLS 1.3 encryption (typically 30-100ms).
Time to First Byte (TTFB)
The web server processing the request and sending the initial HTTP response header back to the client.
Frequently Asked Questions
What is a good response time for a website?
Under 200ms is considered fast, 200ms to 500ms is standard, and anything above 800ms typically indicates database bottlenecks, missing CDN caching, or server resource exhaustion.
Why does an ICMP ping differ from an HTTP ping?
Traditional network ping uses ICMP packets at the network layer (Layer 3/4). Modern websites behind Cloudflare or AWS CloudFront often block ICMP. ExpiryHawk performs Layer 7 application pings testing full HTTP/HTTPS response codes.
