      DC24
      - DC24 went well, objectives reached. 
      - Edoardo: NOTED was running dry for the whole duration. On the last hreee days it was taking real loadbalancing actions with PIC, TRIUMF and KIT. Unfortunately the links were never congested, so there was no real practical gain.
      - Tom: Fermilab and Caltech, tested traffic prioritazion with Sense. Positive results.
      - Shawn: WLCG is  putting together a document to summarize all the leson learnt. One good thing that was clear is that there was no issue with the WAN. No congestions were seen on the long distance link. There were some problems on the local networks at sites, but not on the WAN
      - Bruno: KIT had a third 100G link to CERN that allowed to avoid congestions
      - Firefly dashboard https://public.stardust.es.net/goto/iRsxh8oIg?orgId=1
      - Yatish: for ESnet High Touch, we archived all the data collected during DC24. It can  be analyzed later for in depth analyses
      - Katy shows the stats of FTS for all the sites. It reached 2.5Tbps for some short time on the last day, which was the target of the Flixeble model. The target of the minimal model was reached constantly. 
      - Shawn: we didn't reahe the target to run at 2.5Tbps for 48h, so we may run another mini-challenge before May
