I'm having a bit of a problem with the new 1.7.8 dev builds. Whenever I try to load my remote server, it throws a bunch of AuthenticationUnavailableExceptions/IOExceptions while trying to convert the player data files (I assume this because the stack trace mentions the class PlayerDatFileConverter). It also reports a 503 response code for https://api.mojang.com/profiles/page/1. While this at first seemed like an issue with Mojang's servers, I'm having absolutely no trouble starting up a local server (which has player data stored on it). I would assume that this is an issue with my host, but I wanted to check whether it was an isolated issue or not, and possibly get some advice for fixing it. It's also worth mentioning that the issue isn't limited to Bukkit and occurs with the vanilla server as well, but I figure this is the best place to ask for help. Edit: The problem magically fixed itself. Still confused as to why it only happened on my host's servers, though.
