DNS Setup Issues
Common DNS problems and how to resolve them.
DNS not propagating
After updating DNS, changes can take time to propagate globally.
What to check:
- Verify you updated the correct DNS zone (check for typos)
- Ensure you saved/applied the changes at your DNS provider
- Check if your registrar has a separate DNS management panel
- Wait up to 24-48 hours for full global propagation
# Check current DNS resolution
dig yourdomain.com +shortTip: Use a DNS propagation checker like whatsmydns.net to see if changes have propagated to different regions.
CNAME vs A record confusion
Using the wrong record type can cause issues.
For subdomains (www, cdn, etc.)
Use CNAME record
For root domain (@)
Use A record or ALIAS/ANAME
Note: Some DNS providers don't support CNAME at the root domain. Check if they support ALIAS or ANAME records as alternatives.
Conflicting DNS records
Multiple records for the same hostname can cause unpredictable behavior.
Solution:
- List all existing records for your domain
- Remove any old A or CNAME records pointing elsewhere
- Keep only the Fast DNS records
- Delete any conflicting MX records (email should be separate)
Cloudflare proxy enabled
If you're using Cloudflare for DNS, make sure the proxy (orange cloud) is disabled.
Problem: Orange cloud enabled = Cloudflare proxies traffic, which conflicts with Fast Edge Cache.
Solution: Click the orange cloud to turn it grey (DNS only). This lets Fast handle the caching and optimization.
