Background downloader not downloading

I have the background dowloader installed and set to check for items to download once a day. I am using SW 2012 SP3 and would have expected it to have downloaded SP4 by now but it hasn't. I know that I can download it manually but was just wondering if anyone else had come accross this situation. I have spoken to my VAR & they just said that it could be due to the fact that so many people were downloading the service pack.
