I don't think this is just you then
One of the top guys on my team was making 11+M PPD almost all on CPU and he has basically dropped off today as well.
Yeah, rebooted the rig just to be sure, and same outcome:

None of the servers are giving WU's for "my configuration", but that could very well be for all configurations, because I have 2 Ryzen rigs, and 2 old Sandy Bridge Xeon rigs, and none are getting CPU work units right now.
