DNS Health
Nameserver redundancy check
A domain should have at least two nameservers, ideally on separate networks, so one outage does not take everything down.
Check this on your own domain now. It is free with a DomainGuard account, reads only public records, and gives you a report you can send to whoever runs your website.
What we look at
We count your nameservers and check whether they sit on more than one network.
Why it matters to your business
With a single nameserver, or several on the same network, one fault makes your website and email unreachable for everyone. Redundant nameservers are free with almost every DNS provider.
How to fix it
- Publish every nameserver your DNS provider assigns (usually two to four).
- If you run your own DNS, add a secondary provider on a different network.
If you would rather not touch DNS or server settings yourself, forward this page and your report to whoever manages your website, or ask us to do it.
Keep an eye on it
A one-off check tells you how things stand today. On Starter and up, DomainGuard re-checks the domains it watches every day and alerts you in the app when something important changes, so you hear about it before a customer does.
