      Outreach
      - CHEP paper revision was submitted 
      - Updated our web page (let me know if I missed some past/upcoming events)

      Collectors
      - Collectors meeting doodle sent - plan to meet in the next two weeks
      - Kafka input/output plugin (A: Andy Lake)

      Registry & Domain
      - Agreed to finalize this before mid July when the current registration expires

      Dashboards 
      - Deployed OpenSearch at CERN with splitter collector sending to GEANT, ESnet and also locally
         - Running local collector, OpenSearch + Grafana on a single bare metal (Xeon(R) CPU E5-2620 v4, 128G RAM)
            - Fireflies coming from EOS CERN and RAL - around 20M/day (~5GB/day); 250 avg. events/minute (100-1000 range)
      - Changes in the local collector
         - calculates duration and throughput
         - adds CRIC sites, countries, tiers
         - adds experiment/activity names from api.scitags.org
         - fixes src/dest IPs and ports if bytes received > sent 
      - Two new dashboards
         - R&E dashboard - motivated by WLCG transfers dashboard
         - Site dashboard - looks at performance of the storage system (pool nodes)

      dCache 
      - Correction: Support for Scitags released in 11.0.1 (https://github.com/dCache/dcache/releases/tag/11.0.1)
          - This contains full implementation, but 11.0 is not a golden/stable release, so it will take time before sites update
          - RPM Backported to 10.2.12 is available at 
                https://gitlab.desy.de/dcache/dcache/-/jobs/828164/artifacts/file/packages/fhs/target/rpmbuild/RPMS/noarch/dcache-10.2.13.bf8428d-1scitag.noarch.rpm
      - Testing to start at AGLT2

      EOS (CERN)
      - Found an issue with exporting ATLAS fireflies, related to recent changes in xrootd 5.8.0 - this has been fixed at CERN via config change
      - There is also some processing issue at the CERN site-collector as some fireflies are still missing (under investigation)

      flowd-go
      - Testing at CNAF
