Minecraft exits on 503 for http://s3.amazonaws.com/MinecraftResources/

Crash happened on loading a game, while chunks where being loaded & displayed (not all the world was visible). I guess the "Unexpected end of file from server" error comes from server dying from the first "Server returned HTTP response code: 503 for URL: http://s3.amazonaws.com/MinecraftResources/" error. Loading that URL in a browser right after the crash works (amazon hickup ?). Minecraft could probably retry instead of dying.
