Verify if your website or server is online right now. Measure Time To First Byte (TTFB), DNS lookup latency, SSL handshake speed, and global multi-region accessibility.
Connecting to server and capturing latency waterfall.
Unable to connect to host.
Even 5 minutes of server downtime can cost thousands in lost sales and cause search engine bots to temporarily de-index your high-value landing pages.
Ensure checkout funnels, lead contact forms, and SaaS dashboards remain reachable 24/7/365 across every timezone.
Google Core Web Vitals heavily weigh server response time (TTFB). A response time under 200ms ensures peak crawl efficiency.
Detect memory leaks, database connection bottlenecks, and origin host failures before your customers notice.
According to Google Lighthouse and Core Web Vitals standards, an optimal Time To First Byte (TTFB) is under 200ms. TTFBs between 200ms and 500ms are acceptable, while anything above 600ms requires server caching or database tuning.
99.9% ("three nines") allows up to 8.76 hours of downtime per year. 99.99% ("four nines") high availability allows only 52.6 minutes of downtime per year.
HTTP 200 (OK) and 301/302 (Redirects) indicate the server is functioning properly. HTTP 500, 502 Bad Gateway, 503 Service Unavailable, and 504 Gateway Timeout indicate server crashes, overload, or reverse-proxy misconfigurations.
