Custom 404 page for fission live

[bnchrch]

NB: Feature requests will only be considered if they solve a pain

Summary

Problem

• Our 404 page is bland
• some users will hit a 404 for their site while dns propogates

Impact

• degraded user experience

Solution

Describe the solution

Detail

• use nginx to catch 404s from the ipfs gateway and serve a custom 404.html page.
• the page should let users know that fission is currently building the interwebs and to be patient

Road Blocks

Go-ipfs needs to expose this functionality

https://stackoverflow.com/questions/1024199/nginx-customizing-404-page

so until the above PR is merged we will need to use nginx to capture out going status codes

@bmann would you say that ipfs-404.html addresses this?

https://github.com/ipfs/go-ipfs/pull/4233

Users will still see “bare” IPFS 404s unless they have manually put in an ipfs-404 file in their tree.

Tag this with “proxy” and backlog for now.
