One last update before I go to bed and disapear for 12 hours.
The backlog has went from 1.2 mil at its peak earlier today to 0,4 mil now after we reconfigured things. It is steadily going down and should have everything up to working order before I get up.
One or two people were able to get images loaded after a VERY long wait. So while images still arent working it seems very likely related to the backlog. In a few hours when the backlog clears I expect image uploads should work again. If not I will check what the problem is in the morning.
Other than that most things appear to be working and everything should be functional soon.
