This usually points to a performance or network-related issue rather than a single website problem. It can happen due to slow DNS response, heavy cache buildup, extensions interfering with page loading, or high memory usage causing the browser to freeze temporarily. You could try clearing cache, disabling extensions, testing in private mode, or switching DNS (like Google or Cloudflare) to see if loading speed improves. If it continues across multiple sites, it’s more likely a browser/system performance issue.
