Operational issues:

• LHCb drained on Saturday due to problems with LHCb Bookkeeping.
  • The number of running jobs is still a bit lower than usual, probably due to CMS taking over the farm?
• A few failed uploads to ECHO from external sites yesterday afternoon and this morning.
  • The errors are hostname resolution failures -- were there any known DNS-related issues?
• A few buggy WG Productions were submitted by LHCb, resulting in job failure spikes
  • Linked to xrootd 5.1.1 client, which cannot execute vector reads for xrootd-based storage properly.

News:

• Token-based ETF test for ARC CEs added to LHCb preprod environment (see e.g. here)
  • So far the tests are failing for almost all sites
  • At RAL LHCb token configuration seems to be missing in the ARC config. GSTSM-521.
