RAL Tier1 Operations Report for 26th March 2019

Review of Issues during the week 18th March 2019 to the 26th March 2019.
  • All very quiet at Tier-1 with nothing of note to report - until Friday afternoon, then the Security Challenge started...!
  • With reference to the current Security Challenge, at time of reporting, RAL-LCG2 have not yet found any evidence of the DN successfully running batch work or accessing our storage. We do see the incoming batch jobs and we are investigating why these seem not to have run. As yet we have not found any access to the IPs listed in the initial communication.
  • Tier-1 did not a problem on our site Argus server on Saturday around 13:20UTC when the Argus PAP server stopped. It was restarted after a callout. At present we do not believe this is related to the challenge.
