  VO Liaison CMS 10m
  
  Speaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))
  
  Some failures on the AAA machines - Katy restarted the services again on Tuesday night and SAM tests are green again since then.
  
  Intermittent failures on ARC-CE tests seem more regular in the last weeks.
  
  Still some problems with passing token/CE tests. It appears to have worked once, but not again!
  
  Job performance is good.

  A sandbox that introduces FQAN-based authentication is applied to the host
  
  May need some "linting" though
  
  Operational issues:
  
  Faulty changed rolled-out to preprod farm, breaking xrootd-proxy
  
  Fixed the next day
  
  There was a spike of failed uploads from RAL WNs to CERN yesterday
  
  Mostly affected RAL->CERN channel, but other sites have a few failures as well, so probably not our problem.
