Example is down

[evisong]

Hi, thanks for this great project.

I've been reading the doc and happened to find the example https://server-timing.now.sh/ (auto redirected to https://server-timing.vercel.app/) is down, the webpage shows:

404: NOT_FOUND
Code: DEPLOYMENT_NOT_FOUND
ID: sin1::cpght-1671003668363-b84e01d8e597

[server-timing.vercel.app might be available. Click here to learn how to assign it to a project.](https://vercel.com/docs/custom-domains#assigning-a-domain-to-a-git-branch)

Would you please fix it?

Thanks.
