Things has been rolling on for a very long time now without any major downtimes or issues when it comes to the game and site, shouldn't be surprised if things like these might occur once in a while. I might be wrong but I do believe the harddrives we have on the server has been running non stop for about a year without any rest under more or less heavy load.
To my understanding the issue we have right now might remain for a bit longer, but no need for anyone to fret since the game is where it is and the forum is still online.
However you don't need to save these indexed files onto your computer, cancel it and just try the link again a few times even if needed.
