That \u201cDNS Server Not Responding\u201d error can hit at the worst moment. A site that was loading a minute ago suddenly stops, a mail client stalls, or your own VPS looks alive but nobody can reach the domain. In Moldova, that matters more than it used to, because the World Bank reports individual Internet use rose from 31.8% in 2010<\/strong> to 76.7% in 2023<\/strong> (World Bank-linked Moldova DNS troubleshooting note<\/a>). When DNS fails, the physical connection can still be fine, but browsing, email, and cloud access all break at the name-resolution layer, which is why a structured approach beats random clicking. For SMB teams, that's the same reason guides on solving DNS problems for SMBs<\/a> stay relevant.<\/p>\n

If you manage your own server, the right question isn't just \u201cWhy is DNS down?\u201d It's \u201cWhere is the break, client, resolver, routing, or server config?\u201d Public troubleshooting guidance used in the region usually starts with local cache flushes, resolver changes, and service restarts, because many incidents are local and recover quickly. The practical trick is to move from the easiest checks to the deeper ones without skipping the evidence in between. That keeps you from changing the wrong file on a VPS when the actual issue is a broken router cache or a blocked path to the resolver.<\/p>\n

1. Check Connectivity with Nslookup and Dig<\/h2>\n

Start with the fastest proof of whether name resolution works at all. Nslookup<\/strong> and dig<\/strong> are the two commands I reach for first on Windows, Linux, and macOS, because they tell you whether the problem is the domain, the resolver, or the route between them. A plain nslookup domain.com<\/code> gives a quick answer, while nslookup domain.com 8.8.8.8<\/code> tests an alternate resolver directly. dig domain.com +short<\/code> is cleaner when you only need the result, not the full explanation.<\/p>\n

For a VPS owner, this matters when a WordPress site points to the wrong IP after a migration. If dig<\/code> returns the old address or no answer at all, the server may be fine while the nameserver records or local resolver are not. If you host on AvenaCloud, checking NS records with dig<\/code> is a practical way to confirm the domain points to the right nameserver set before you touch the application layer. That's also how you separate a broken website from a broken lookup path.<\/p>\n

Use the query, not the guess<\/h3>\n

A useful pattern is to compare multiple public resolvers, not just one. If one resolver works and another doesn't, the issue is probably upstream of your machine, not inside the site. Public examples often use Google DNS 8.8.8.8<\/strong> and Cloudflare 1.1.1.1<\/strong>, and that comparison is useful because it rules out provider-specific failures without changing your server configuration.<\/p>\n

Practical rule:<\/strong> if ping<\/code> by IP works but nslookup<\/code> fails, you're looking at DNS reachability or configuration, not a general internet outage.<\/p>\n<\/blockquote>\n

A short run of commands often settles the question fast:<\/p>\n
