A SERVFAIL response after changing DNS providers, nameservers, or DNSSEC settings can have several causes. Review the troubleshooting steps in https://www.whatismyip.com/servfail-dns-dnssec-delegation/?utm_source=community&utm_medium=social&utm_campaign=pipeline-377&utm_content=topic(https://www.whatismyip.com/servfail-dns-dnssec-delegation/), then share what your tests showed.
- Which test identified the failure: comparing resolvers, tracing the delegation, querying authoritative servers, or validating DNSSEC?
- What ultimately fixed the problem?
- Did the failure affect every resolver, or only a particular resolver or network?
Helpful technical details include the DNS record type tested, whether DNSSEC was enabled, the general type of DNS change, relevant response codes, and redacted dig or delv results.
Please remove public IP addresses, sensitive domain or customer names, email addresses, account information, credentials, and internal network details before posting diagnostic output or screenshots.
