DNS-SINGLE-NS
Only one nameserver is delegated
What it means
A single nameserver is a single point of failure; when it is down, everything under the domain disappears.
How to fix it
- 1Add a second nameserver, ideally at a different provider or network.
Re-check after the change
DNS changes can take up to the record's TTL to be seen; use Re-run on the result page to bypass our 10-minute cache.
