I have a problem with my DNS lookup.
I just switched part of my project to netlify. I setup a dev server and point my sub-domain to the new address (adding the nameserver).
The app address works fine https://competent-bardeen-40f1fc.netlify.app/
But the domain access is slow: dev-site.colofon.io
I have a ~10s DNS lookup the first time. If I refresh, it’s normal.
The HAR file. Don’t know if it’s of any use: http://files.colofon.io/dev-site.colofon.io.har
