      LHCONE 20m

      SC25

      - SCinet is asking for proposal for SC25. Discussing a test at 1.2TBps for scitags from UVic
      - SC24 had SciTags at 800G. SC25 could be SciTags at 1.2Tbps. Tristan: we have a Gen5 server and we can get a second one.
      - Marian: we should do it with flowdGo. But we may not have any 400G hardware by that time.

      LHCONE

      - Edoardo will report about the SKA joining LHCONE at the WLCG Coordination Board on Thursday

      Next meeting 3rd of June.

      Outreach
      - CHEP paper - received comments (https://indico.cern.ch/event/1338689/papers/6010796/)
           - Paper is at https://www.overleaf.com/read/jwwxfcqcpqqs#3ae27b
      - Updated our web page (let me know if I missed some past/upcoming events)

      Collectors
      - Missing Kafka input/output plugin (A: Andy Lake)
      - Meeting with GEANT took place, was very positive, they're arranging VM in Frankfurt (our contact is Daniela Brauner from RE team)
            - We agreed to follow up with monthly meetings
      - UK collector should be back as well

      Registry & Domain
      - Meeting with Karl on migration of the domain and services to Internet2
      - We agreed to finalize this before mid July when the current registration expires
      - API services will be hosted on AWS (API services for WLCG will continue to work from https://scitags.docs.cern.ch/api.json)
          - We also discussed possiblity to create collector.scitags.org that would redirect based on geo-location of the client to a us/eu/uk collector

      Dashboards 
      - Following CMS xrootd configuration campaign we now have some sites sending fireflies but not showing up in the dashboard (CNAF, RAL)
         - This is due to missing site mapping - needs an update on the site mappings 
      - Deploying OpenSearch at CERN to be able to work on the site dashboard
         - Plan to look at adding site mappings from WLCG CRIC (could benefit also R&E collectors/dashboards)

      dCache 
      - Support for Scitags released in 10.2.12 (https://github.com/dCache/dcache/releases/tag/10.2.12)
          - This contains full implementation - including usage and storage access statistics 
      - AGLT2 will deploy and test

      EOS (CERN)
      - Requested to change the configuration, so that we start tracking flows not coming from FTS/Rucio (fallback mechanism based on directory access) 
      - This has been deployed and works fine (all flows coming from CERN EOS are now marked via fireflies)

      flowd-go
      - Packaging in koji done - next step would be to deploy and test (maybe at CNAF ? or at QM)
