So have people just stopped making purchases on GPU max?

I have barely gotten any leased work at all over the last week, and yes, my miners are priced well below the the leasing maximum.
I'm considering taking all my miners offline since there isn't any work available to make up for the increased rejects mining through GPUmax on my offline pool. It was nice while it lasted, but I had a feeling the ratio of miners to purchasers was going to grow way out of sync.

Last couple of days there has been work, one thing to check is your miners after the update it had the only work on private pools on by default on my miners perhaps this is the case for yours as well.
