I think it's dead, since yesterday morning I haven't been able to get my block erupters to stay connected to it very long.  The past few weeks they've been saying they're not receiving work fast enough, but last night they went completely silent.  This morning I rebooted my rPi and got no work at all from the pool.  It sucks cause I was trying to mine up to the 0.01 so I could withdraw.  I got it up to 0.009 over the past month or two.  So if the owner of the site could get with me, I'd love the last couple months of electricity to not be in vain.
