We have made changes to ensure the vercel.com and vercel.app domains are accessible once again from China after a block was placed from within the country.

For those impacted that are using a custom domain on Vercel, the issue can be mitigated by changing your A record value pointing to Vercel from 76.76.21.21 to 76.223.126.88.

While we have resolved the issue impacting CNAME records, we still recommend changing cname.vercel-dns.com to cname-china.vercel-dns.com for additional redundancy.
