Namecheap controls both the domain name settings and the dns (if you use theirs). The moment you switch the nameservers for the domain, they immediately purge the records from their DNS.

So, when you point to new nameservers, anyone pointing to namecheap's dns during propagation will get SERVFAIL.

It sounds absurd... but I've gone back and forth with support about it, with no solution.

Interesting tip. I'm taking away the fact that I should transfer the nameservers away immediately after buying/transferring a domain (for Cloudfront, I presume?). Other than that, and ColdFusion hacks aside, my experience with them has also been fantastic.

Ah, that makes more sense. Haven't used their DNS - do they let you drop the TTL, at least?
