Before you panic and call your internet provider, try a simple cross-check: open another site or two. If those load fine, the problem is likely with the specific site you're trying to reach. Use a tool like Down For Everyone Or Just Me, which will tell you if the site is globally inaccessible. If it's just you, try clearing your browser cache or switching DNS servers to see if that resolves the issue.
