Run an instant diagnostic scan to check live DNS records, email authentication, and SSL security. Catch errors early to prevent silent downtime and keep your website running smoothly.
What Does Our DNS Health Report Inspect?
BigCloudy Domain Health Checker runs a deep, real-time diagnostic across your core network records to ensure complete stability, reachability, and security. Here is an overview of what the report audits:
-
Authoritative Nameservers & Zone Delegation
Confirms that nameserver delegations at your domain registrar match your active zone records. It verifies rapid response times across IPv4 and IPv6, validates identical serial numbers, and flags query timeouts.
-
SOA Parameters & Zone Standards
Audits primary master nameservers, administrator contacts, refresh rates, and retry intervals against standard RFC rules to prevent caching inconsistencies.
-
A & AAAA Record Resolution
Verifies that your apex domain and www host route accurately to live server IP addresses, ensuring visitors reach your site without latency or connection drops.
-
Mail Exchange & Routing (MX)
Validates mail server hostnames, priorities, and routing paths to ensure inbound business emails arrive reliably without bouncing.
-
Email Security & Inbox Delivery (SPF & DMARC)
Audits authentication TXT records to protect domain reputation. It checks SPF syntax, enforces the 10-lookup limit, and evaluates DMARC alignment to stop spoofing attempts.
-
Glue Records & Server Integrity
Inspects parent-level glue records to prevent circular routing, detects stealth nameservers, and verifies that open DNS recursion is disabled.
-
WHOIS Lifecycle & Registry Locks
Monitors domain registration dates, expiration timelines, DNSSEC keys, and registrar transfer lock status (clientTransferProhibited) to safeguard domain ownership.
-
SSL & TLS Certificate Health
Evaluates TLS handshake ciphers, SAN hostname coverage, root trust chains, and expiration countdowns to ensure seamless HTTPS connections without browser security alerts.
How Continuous Monitoring Keeps Your Site Online
A single test only shows how your domain is performing right now. Web settings can break without warning: server caches get stuck, certificates fail to renew, or a wrong DNS record can knock your site offline while you sleep.
Continuous monitoring runs in the background so you never have to guess:
-
Auto-Tracking SSL Expiry Dates
Certificates expire every few months. Continuous checks watch your validity window across your main domain and subdomains, giving you plenty of time to renew before browsers show a warning screen.
-
Reliable Email Delivery
Mail filters change rules frequently. Ongoing monitoring checks your MX, SPF, and DMARC records to make sure your proposals and daily emails reach client inboxes instead of the spam folder.
-
Catching Unwanted DNS Changes
Accidental edits or unauthorized record shifts can redirect your website visitors. Monitoring spots any unexpected update to your A, AAAA, or nameserver records right when it happens.

Frequently Asked Questions
How do I check if my domain DNS is working properly?
Enter your domain name into the status tool to run a live lookup. The report checks whether your authoritative nameservers, root A records, and SOA settings are active and resolving correctly across global networks without errors.
Why do my domain emails keep going to spam?
Emails usually land in spam when authentication records are missing or broken. Mail providers like Google and Yahoo require a valid SPF text record, active DKIM keys, and an aligned DMARC policy to confirm your identity and prevent spoofing.
What causes a “Connection Not Private” SSL error on my website?
This browser warning triggers when an SSL certificate expires, the domain name does not match the certificate SAN list, or intermediate chain certificates are missing. You can fix it by reissuing the certificate or enabling automated renewals through your host.
How long does DNS propagation take after changing nameservers?
DNS updates typically take between 15 minutes and 24 hours to spread worldwide. The speed depends on the Time-to-Live (TTL) settings of your previous records and how frequently local internet service providers refresh their DNS caches.
What is the difference between a one-time DNS check and domain monitoring?
A manual check only shows your domain configuration at the exact moment of the test. Ongoing monitoring runs automated scans 24/7 to alert you instantly if your site goes down, records get altered, or an SSL certificate approaches expiration.
