The site is there when I go directly. I’m using your auto-configured DNS. The browser claims “the site took too long to respond” when I go via the custom domain.
Note, I have the same problem with my branch deploys. They broke first, and then the main site went down a few days later. Again, each of the *.netlify.app domains work; only the custom domains fail.
nslookup seems to be resolving DNS for each of the custom domains. I don’t know what the right IP is supposed to be, but I’m at least seeing one. From there, it heads into the opaque land of your DNS internal config / server config. Please help!
