We've recently encountered a few problems in ATLAS in which jobs fail to obtain Conditions data from fail-over Squid or Frontier sites. Could all T2 and participating T1 site administrators please have a look at the following matrix and ensure that the specified fail-over pairings for your sites reflect reality: https://twiki.cern.ch/twiki/bin/view/Atlas/T2SquidDeployment#EGEE_Deployment

In addition, there may be some related work involved in ensuring the fail-over sites and their worker nodes are permitted to use your site Squid and/or Frontier resources. This may require the addition or modification of service access control lists and firewall rules, and a subsequent restart of services, which may result in a brief down-time period.

Please let me know of any questions or problems that may arise.

Thanks, ~John jd@bnl.gov
