Fix Google Sites DNS Error

I have just launched a new Google Sites website and pointed my custom domain—managed at GoDaddy—toward it. Instead of loading, visitors now see an “Invalid DNS” message. I haven’t had the chance to double-check every required record, so I’m unsure which CNAME, TXT or A record may be missing or mis-typed.

Here’s what I need:
• Audit the current zone file in GoDaddy.
• Add or correct every record Google Sites expects, including verification and HTTPS support.
• Monitor propagation and confirm the domain resolves worldwide without errors.

Please document the exact changes you make so I can keep them on file. Once the site loads cleanly in a browser (no DNS errors, SSL padlock present), the job is done.
