It passes validation. When I open `http://cdn.ampproject.org/c/s/MY_URL`, it's correctly displayed, but after a few refreshes I get 404 page (the one with sad phone). I can't understand the root of this problem. I've got two possible reasons:\r\n\r\n- There's a bug in my impl of auth & pingback endpoints - wrong CORS headers, which doesn't affect validation, but throws an error in runtime\r\n- Page has noindex in its meta (which is required for now)\r\n\r\nCould they result to 404s? Would appreciate any hints.\r\n"},"comment":{"url":"https://api.github.com/repos/ampproject/amphtml/issues/comments/247099605","html_url":"https://github.com/ampproject/amphtml/issues/4881#issuecomment-247099605","issue_url":"https://api.github.com/repos/ampproject/amphtml/issues/4881","id":247099605,"user":{"login":"ericlindley-g","id":16807766,"avatar_url":"https://avatars.githubusercontent.com/u/16807766?v=3","gravatar_id":"","url":"https://api.github.com/users/ericlindley-g","html_url":"https://github.com/ericlindley-g","followers_url":"https://api.github.com/users/ericlindley-g/followers","following_url":"https://api.github.com/users/ericlindley-g/following{/other_user}","gists_url":"https://api.github.com/users/ericlindley-g/gists{/gist_id}","starred_url":"https://api.github.com/users/ericlindley-g/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ericlindley-g/subscriptions","organizations_url":"https://api.github.com/users/ericlindley-g/orgs","repos_url":"https://api.github.com/users/ericlindley-g/repos","events_url":"https://api.github.com/users/ericlindley-g/events{/privacy}","received_events_url":"https://api.github.com/users/ericlindley-g/received_events","type":"User","site_admin":false},"created_at":"2016-09-14T17:53:46Z","updated_at":"2016-09-14T17:53:46Z","body":"@kozlice Do you have an example of a page having this issue?"}}
