Priority fixes for vercel.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 1 external script without async or defer.
Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
On Next.js: Use the next/script component with an appropriate loading strategy.
50% of Web Hosting & Infrastructure peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

Priority 2 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
33% of Web Hosting & Infrastructure peers do this.
Priority 3 · Harden
DNSSEC signed
Observed: No DS record was found for vercel.com at its parent zone, so its DNS answers are not DNSSEC-signed.
What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.
28% of Web Hosting & Infrastructure peers do this.

Priority 4 · Enable
Reachable over IPv6
Observed: No IPv6 (AAAA) address was published for vercel.com.
What to do: Enable IPv6 at your CDN or host and publish the AAAA record it provides.
43% of Web Hosting & Infrastructure peers do this.
