Internet Health Check: Connection Monitor & Speed Test

Outage log + Wi-Fi connection monitor: free speed test, latency tracking, and ISP evidence reports.

Is your Wi-Fi down, your ISP slow, or just one website offline? Internet Health Check is an internet connection monitor, outage logger, and free speed test for Chrome and Microsoft Edge. Monitor connection health, identify interruptions, track latency, and build a useful record of network problems — all without creating an account. FREE INTERNET MONITORING & SPEED TESTS • Free speed test — measure ping, download, and upload directly from the popup. • Live connection health — see latency, uptime, dropouts, public IP, and offline time. • Outage history — review timestamped connection interruptions and export records to CSV. • Guided "Is it just me?" diagnosis — check independent services, compare recent local monitoring patterns, and get practical troubleshooting steps. • Clear confidence levels — understand what was measured, whether problems repeat, and what remains unknown. • Custom connection test endpoint — monitor a website or service you choose. • Toolbar status indicator — see connection health and latency at a glance. • Desktop notifications — receive alerts when connection interruptions and recoveries are detected. GUIDED NETWORK TROUBLESHOOTING When your connection becomes unreliable, Internet Health Check helps you investigate: • Is the wider connection unavailable, or is one website having problems? • Have similar interruptions occurred recently? • Is latency unusually high compared with recent observations? • What should you try next? The guided diagnosis explains its observations and suggests useful next steps. Important: Browser-based checks cannot definitively identify whether a problem is caused by Wi-Fi, your router, DNS, your ISP, or a remote service. EXPLORE YOUR CONNECTION HISTORY The dashboard provides: • Realtime — watch latency and connection changes. • 24-hour uptime overview — available for Free users. • History — review recorded outages, instability, and recovery times. • Insights — understand connection patterns and performance trends. • Monitoring gaps — distinguish actual recorded outages from periods when monitoring was unavailable. Detailed per-interval uptime, issue counts, and average latency are available with Pro or an active trial. Monitoring operates while the browser can run the extension. Sleep, browser shutdown, and other unmonitored periods are not represented as confirmed outages. ISP EVIDENCE REPORT Need to explain recurring internet problems to your provider? Internet Health Check helps build a factual record using your actual local measurements. The full Pro Evidence Report includes: • A timestamped outage timeline. • Outage durations and offline totals. • A clearly defined reporting period and time zone. • Explicit monitoring gaps. • Individual speed-test records. • Measured speeds compared with the broadband plan speeds you enter. • Patterns of recurring interruptions when sufficient observations exist. • A print-ready report suitable for saving as PDF. Report periods follow available retained history: 7, 30, 90 days, or all retained history, depending on your settings. Free users can access one watermarked Evidence Report preview when enough actual observations are available. The preview covers the last 7 days and up to five recorded outages. These reports describe observations from your browser and device; they do not establish responsibility for a network problem.

PRIVACY FIRST Internet Health Check is designed around local monitoring. • No account required for core features. • No browsing-history permission. • Your recorded monitoring history and settings stay in browser-local storage. • Product analytics is optional and disabled by default. • Consented anonymous analytics does not include browsing history, monitored URLs, connection samples, speed-test results, or email content. • Connectivity checks communicate with public network endpoints. • Speed tests use Cloudflare's public speed-test service. • Public IP lookup uses api.ipify.org. • License activation and purchases use the companion website. WHY THESE PERMISSIONS? • alarms — schedule background connection checks. • storage — save monitoring records and settings locally. • notifications — show connection interruption and recovery alerts. • Optional host access — let you configure additional test endpoints when you choose to. Internet Health Check does not request permission to read your browsing history. WHO IS IT FOR? • Remote workers troubleshooting unreliable calls. • Gamers investigating lag spikes and connection interruptions. • Video callers experiencing unstable connections. • Home broadband customers documenting recurring outages. • Chromebook users who want browser-based connection monitoring. • IT professionals gathering timestamped connection observations.
