My blog is deployed on Vercel, but access from mainland China is very slow, so I set up an optimized domain to speed it up and improve the experience.
Configure the domain
Although Vercel assigns a domain after you create a project, it performs poorly and is also hard to remember. First, go to Vercel settings and configure a domain in the Domain section.
Optimized domain
Reference domains for Vercel optimization:
vercel.cdn.cyfan.toprecommendedvercel.cdn.yt-blog.topvercel-cname.xingpingcn.top
For DNS records:
A record —> 76.76.21.21
CNAME —> any one of the optimized domains above

Much better now…
