> I created a repo but can't look at it because I get a 404 for it.

I remember back in early GitHub days this used to happen too, as the repository was asynchronously created but the redirect was immediate, then after a few seconds you refreshed the page and it was there. At one point they added the interstitial that I think is still there, that basically does the "waiting then redirect" for you.

Oh yes, seems like that's it. I can now view the repo. A bit annoying when creating a repo redirects you to a URL that will give you a 404 initially (and at least for minute or so, that's how long I tried).
