Ongoing analysis of US Tier-2 LHCONE network use being explored with ESnet, comparing/contrasting the ESnet metrics with the ATLAS and CMS numbers.   Today is a follow-up meeting to cover ATLAS numbers.  See spreadsheet at https://docs.google.com/spreadsheets/d/1zCdr-9avH-aDtXDTNGli1HZ245LETJud6amDn4S_Azg/edit#gid=895412619 

The perfSONAR v4.1.1 update is out.   Fixes initial issues with 4.1.   

The OSG/WLCG "meshconfig" (now "pSConfig") GUI running at AGLT2 MSU has some IPv6 connectivity issues.  Some perfSONAR instances that are dual-stacked and NOT on LHCONE don't have connectivity to the psconfig.opensciencegrid.org host.   Working with MSU networking to see about what is wrong and how to get it fixed.
