171.64.65.56 not responding

I have a couple SMP clients that have been trying to upload to 171.64.65.56, but the server is not responding. On folding forum in the 171.64.65.56 not responding thread it's been reported that WUs are uploading and downloading; that may be the case but server 171.64.65.56 is having problems, none the less.

Yeah had a couple sitting there since Sunday waiting to upload and not got new WU,s

But they went through 30mins ago so Server 171.64.65.56, is Back Up for now!!!
