My app is getting 404 DEPLOYMENT_NOT_FOUND error even on .vercel.app domain

[dianagsgs]

Summary

I noticed my site https://www.labestiaradio.com/ was not loading (sometimes partially, sometimes fully) and returning 404 errors...
I went to check if the vercel domain: https://labestia.vercel.app/ was working, and I am also getting 404 errors there.
Sometimes the page doesn't load at all and I see a DEPLOYMENT_NOT_FOUND error code. Sometimes the page loads but some of the resources don't

Any insights on why this might be happening, as far as I know we didn't change our domain config or anything else lately. This started happening today

(p.s. I am new to deploying on vercel)

Hi,

We can see that the website is accessible now. Are you still facing issue?

[dianagsgs]

Thanks! We are no longer seeing this issue... Are there any clues on what happened or what we can do on the application side to prevent this in the future?

This was related to one of our internal changes. No need to take action on your side

I'm experiencing the same on my site: https://www.japanicarparts.com/
It only appears on Google Oauth.
this is the link that i get clicking on Google Sign In, https://carparts-omega.vercel.app/api/auth/signin/google
which was vercel's domain
