Your local device and network might still be showing the old nameservers from their cached copy, even though the actual update is already live globally.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quick Check<\/h2>\n\n\n\n<p><strong>1. Confirm the nameservers were updated<\/strong><\/p>\n\n\n\n<p>Check your domain registrar or control panel and verify the nameservers are set to the new values you requested:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Example format:\nns1.&#091;your-dns-provider]\nns2.&#091;your-dns-provider]<\/code><\/pre>\n\n\n\n<p><strong>2. Check global DNS propagation<\/strong><\/p>\n\n\n\n<p>Use a free public DNS checker tool:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.whatsmydns.net\/\">https:\/\/www.whatsmydns.net\/<\/a> (enter your domain)<\/li>\n\n\n\n<li><a href=\"https:\/\/mxtoolbox.com\/SuperTool.aspx\">https:\/\/mxtoolbox.com\/SuperTool.aspx<\/a> (search for NS records)<\/li>\n<\/ul>\n\n\n\n<p>These tools query DNS servers worldwide. If they show your <strong>new nameservers<\/strong>, the update is complete and live.<\/p>\n\n\n\n<p><strong>3.
