Go ahead, see for yourself: http://game.endless-online.com/server.html.
What does this mean? Probably nothing. It's probably just offline again until it goes back up. Now this will raise that same age-old question that no one can let go of... who is running EO, who is the one doing this? My guess is that it's still certainly Vult. I could be wrong, but either way, whoever DOES own it has to pay to keep the server online. Perhaps it's a monthly fee, and it wasn't payed for the month of November yet, and that's why it went down pretty much as soon as the month started? Just throwing out educated guesses...
