When a website fails to load, the first question is always: 'Is it just me?' This guide explores how to use tools like IsItDownForEveryone to distinguish between local network issues and global server outages. ### Step 1: Check Global Availability The most effective way to determine if a site is down is to check it from multiple geographic locations. Local ISP issues or regional routing problems can often make a site appear down to you while it remains accessible to the rest of the world. Our nodes across North America, Europe, and Asia provide this clarity instantly. ### Step 2: Analyze DNS Resolution If our global check shows the site is UP but you still cannot access it, the issue likely resides with your DNS provider. Try flushing your DNS cache or switching to a public DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1). ### Step 3: Verify with SSL & Ping Sometimes a site is partially accessible but its secure certificates have expired. Use our SSL Checker to see if certificate errors are the culprit behind those 'Connection Not Private' warnings.
