          LHC:
          - Last week was mostly dedicated to special runs (high beta*) and HI commissioning.
          - Continued with HI commissioning afterwards.
          - Smooth Tier-0 processing, mostly in special configurations.

          CERN IAM instances will be migrated from OpenStack to Kubernetes.

          ECDF_CLOUD HammerCloud exclusion.

          Lack of ATLAS jobs (from the beginning of this week)!
          - OX, SHEF, SUSX, ...
          - OX have modified the PERIODIC_REMOVE expression from their arc configuration to allow a bit of tolerance for memory usage.
          - Do other sites need to implement the same?

          Why is the batch farm forcing ATLAS into swap memory @RAL, e.g., https://bigpanda.cern.ch/job/5966764388/?
          - Is this related to the lack of jobs (above)?

          Absence of DURHAM from Job Accounting (UK Cloud) page.

          DAOD-on-demand demo tests ongoing @RAL.

          Storage Resource Reporting (SRR) checks: https://atlas-cric.cern.ch/core/storageresource/list/ ?
          - To make these fairly regular?

          via ADC Ops:
          - Inbound to RAL backlog 175k and growing: https://fts3-atlas.cern.ch:8449/fts3/ftsmon/#/?vo=&source_se=&dest_se=davs:%2F%2Frdr.echo.stfc.ac.uk&time_window=2
          - Max active raised to 400 (James)?
          - Halving raltape-to-ral minactive transfers (100-50) does change per file rate from 13 to 26 MB/s.
