I was in the midst of migrating my namecheap domain from Route53 to Cloudflare. Set up all the DNS records while ignoring the /api/ errors shown at the bottom of the Cloudflare dashboard thinking some ad block setting in my browser was messed up.
Then I realised setting the NS in Namecheap to Cloudflare's nameservers was taking an inordinate amount of time to propagate, and that's when I checked X/Twitter. Set it back to Route53.
I'm planning my transition away for 10 or so subdomains and 30 records.
The only feature I need to research in new providers is: access to Whois ASN numbers, which I insert into HTTP request headers. I use this to tailor my site for .gov and .edu users.
