Google Domains update time

[Conor Keating]

So I just earlier tried adding a CNAME record or two ({*,hostname}.ddns.mydomain -> ddns.mydomain) to my Google Domain, and when I saved the GD page said "Up to 48h to take effect". Is it typically that long of a wait for that info to be up on ns-cloud-c<number>.google.com , or is it (hopefully) less?

The “up to 48h” is for the change to make it to every DNS server in the whole world. Google’s servers tend to be the fastest to update even when the update isn’t made directly with them. (And technically even the Google Domains DNS servers are separate from the Google DNS servers)

 

EDIT: also new records added to a domain update faster than changes to existing records.

That's what I thought (re: the 48h timetable being to propagate through the whole DNS infrastructure). Still though, even when I've pointed drill at the IPs of the Google Domains nameservers, drill hostname.ddns.mydomain doesn't return either a CNAME record for the subdomain or the A/AAAA records for ddns.mydomain.

 

Edit: So as a workaround I've changed wordpress's config to use ddns.mydomain instead of hostname.ddns.mydomain and I'm able to load the demo site outside of my own network.

I created a dns entry for my domain earlier today and google knew it within 5 min, but it took cloudflares dns about 3x longer before it worked.

Right, but again, I was querying Google Domains' nameservers directly, where the update was made directly with them is what I'm trying to get at.
