Looks like the npmjs.com registry is failing to serve many (most?) scoped packages right now. For instance https://www.npmjs.com/package/@prisma/client says "looks like something unexpected occurred! diagnostics id: 81e64be90eba9e6b_912a". And trying to `npm install` such packages times out with an error, "KV GET failed: 401 Unauthorized".
On a side node: How can it be that Google already indexed this thread like 1 minute after creating it? (second hit when searching for 'KV GET failed, 401')
