Anyone else having trouble accessing https://portal.azure.com right now? It currently redirects to the following -- which returns HTTP 404:
https://login.microsoftonline.com/common/oauth2/authorize?resource=https%3a%2f%2fmanagement.core.windows.net%2f&response_mode=form_post&response_type=code+id_token&scope=user_impersonation+openid&state=OpenIdConnect.AuthenticationProperties%3dIR4UiqnbfGLU...&nonce=635827984458888027...&client_id=c44b4083-...&redirect_uri=https%3a%2f%2fportal.azure.com%2fsignin%2findex&site_id=...
I tried clearing my browser cache and using various InPrivate/Incognito browser windows. Same result in both Chrome and Internet Explorer.
