Service Temporarily Unavailable

I have been having an issue with the BC site that I have never had before yet it's been going on for the past couple of hours. I will go to a new page or to submit a message or edit my story and I will get a "service temporarily unavailable" page stating that there is either a maintenance or the server is full. Is it just me or is everybody getting this? it seems to last for 2 or 3 minutes and then lets me back in again.
