The Art of CTO Connectivity Tester runs browser-based network diagnostics including latency measurement, packet loss detection, and bandwidth estimation for troubleshooting connectivity issues.
Frequently Asked Questions
How do you diagnose network connectivity issues?
Start with basic connectivity checks (DNS resolution, TCP handshake success), then measure latency to key endpoints (values above 100ms for same-region services indicate problems), test for packet loss (any loss above 0.1% degrades application performance), and measure available bandwidth. Compare results against your baseline metrics. Common culprits include DNS misconfiguration, MTU mismatches, network congestion, and misconfigured firewalls or security groups.
What is acceptable latency for web applications?
For user-facing web applications, total page load latency should be under 3 seconds, with the server response time (TTFB) under 200ms for same-region users. API-to-API calls within the same cloud region should be under 5ms, cross-region under 50-150ms depending on distance. Database query latency should be under 10ms for indexed lookups. When latency exceeds these thresholds, investigate network path (traceroute), server processing time, and payload sizes as the most common root causes.
