The article notes that DNSimple's ALIAS records avoid this problem. Would the same thing be true of CloudFlare's new "flattened CNAME" records?

I didn't see such a note, but I'm not sure it would be true, either. DNSimple doesn't actually implement a new DNS record type, it simply puts a TXT record on your domain that says "ALIAS for some.fqdn", and presumably it causes their DNS servers to do a recursive lookup for you (to whatever's in the TXT record) when you try and look at the A record for the naked domain. From github's DDoS prevention's point of view…

Anthony from DNSimple here. The ALIAS does synthesize the A record set, but it's the same A record set that is used when a username.github.io domain is resolved, which means it should work fine with Github's DDOS prevention.

The TXT record is only there for informational purposes and could be removed without affecting the system.

Since we have an Anycast network you will also get a result that would be similar to a CNAME resolution, meaning you'll typically get a "close" set of IPs that would be similar to what you would get from the resolution of a CNAME, which ultimately resolves down to A records as well.

Cole with Brace here ( http://brace.io ). We recommend redirecting the apex domain to a "www" subdomain. Note that even using apex CNAME records (Alias records) are still a new idea, and depending on the implementation may reduce reliability or performance. ( https://iwantmyname.com/blog/2014/01/why-alias-type-records-... ) Here are a few resources from our blog that explain the www redirect approach: - http://blog.b…

I also wrote an article about ALIAS-type DNS records for CNAME functionality on naked domains and alternatives last week: https://iwantmyname.com/blog/2014/05/alias-type-dns-records-... Hope it's helpful!

I'm glad to see the turnaround from the original post that IWMN published earlier this year, Timo, thanks for that.

If you’re having trouble with a root domain on Github pages you may want to check out the Hosting product we (Firebase) just announced. It handles naked domains by having your root A record point to an Anycast IP that serves content from a global CDN. It’s lightning fast. We also support SSL (full SSL, not just SNI) and do the cert provisioning automatically for you. Check it out: https://www.firebase.com/blog/2014-0…

Can it handle multiple custom domains like GitHub Pages or is it $49 / month for each an every little static site you want to have on its own domain?
