Patch 6.0.2 background downloader
Yesterday evening the background downloader for patch 6.0.2 became active, serving up around 15GB of patch data. Shortly after the downloader became active Blizzard pulled it offline. Zarhym explains:
It's important to note that Zarhym goes on to say that any data you did download is fine and won't mess up your patching process. There is no need to delete files or anything like that; and you should listen to what he's saying here too, don't go and delete files in your directory over this. Everything will work fine when the correct files begin to be served up again at a later date.
Update: And since this was written, the background downloader has officially begun anew.
