When you change your domain’s DNS settings, it can take some time before the changes are visible worldwide. At DediRock, we often get questions about DNS errors and why it seems to take so long for websites or emails to work after an update. Don’t worry — this is a normal process, and in most cases, it resolves itself. Here’s how you can troubleshoot and speed things up.
1. Understand DNS Propagation
When you update your domain’s DNS (such as pointing to new nameservers or changing A records), the changes need to spread across multiple global DNS servers. This process is called propagation, and it can take anywhere from a few minutes to 24–48 hours.
During this period, some users may reach your new server, while others may still reach the old one.
2. Verify Your Domain Settings
First, confirm that your DNS records are correct:
-
Log in to your DediRock Client Portal and select your domain.
-
Check your nameservers if you’re using DediRock hosting, they should match the details provided in your welcome email.
-
Ensure that your A, CNAME, and MX records are set up correctly.
3. Use DNS Lookup Tools
To check if your DNS changes have propagated:
-
Use tools like DNS Checker to see DNS results from around the world.
-
Compare your records against what you entered in the DediRock portal.
-
If different regions show different IP addresses, propagation is still in progress.
4. Flush Your Local DNS Cache
Sometimes, your device or ISP is holding onto the old DNS data. You can clear it manually:
-
Windows: Open Command Prompt → type
ipconfig /flushdns→ hit Enter. -
Mac: Open Terminal → type
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. -
Browser Cache: Clear cookies/cache or try opening your site in incognito mode.
5. Check for Common DNS Errors
-
Website not loading at all → Likely propagation delay or incorrect A record.
-
Email not working → Double-check your MX records.
-
Subdomain errors → Verify that CNAME records point correctly.
If you’re unsure, our team can verify your DNS setup.
6. Contact DediRock Support
If propagation takes longer than 48 hours or your DNS is still incorrect:
-
Open a Support Ticket in the client portal.
-
Provide your domain name, DNS records, and screenshots of your current settings.
-
Our team will check your DNS configuration and guide you through corrections.
Final Thoughts
DNS changes may feel frustrating because the wait is out of your control, but it’s a normal internet process. By verifying your records and clearing local caches, you can ensure your domain points to the right place faster.
