    Hi,
      
      
      My systems promptly were updated to the new release.  I reviewed
      the Release Notes and didn't see anything that appeared to impact
      my set of Grid tests.
      
      
      However, since Thursday. I've had quite a number of failed
      Throughput tests happen between my hosts.  Till the upgrade, the
      every three hour tests, would come back green (>=.9Gbs) with an
      occasional yellow (<.9Gbps but more than .5Gbps).  Now it seems
      that during business hours I'll have as many as 70 out of 484
      tests fully fail, these mostly clear over night, but come back the
      next day but not necessarily the same host to host failures.
      
      
      I know that the net as a whole is certainly busier during the day
      but why would the historical grids show at most a slow down not no
      'test data found'?

Hi Phil,

Are the other latency/traceroute tests running correctly? I'm not saying this is the same issue but we observe similar behaviour in one of our meshes.

Are you able to run a CLI throughput test between the example two hosts which are failing and provide the output to see the error?

Regards,
