CMSSiteLog25
08. 10. 2010 Phedex agent dying at irregular intervals
CMSSiteLog24
20. 09. 2010 High throughput (~200 MB/s) sustained for ~24h from various sites
CMSSiteLog23
03. 08. 2010 High phedex throughput of ca. 20 TB/day (mainly from FNAL)
CMSSiteLog22
16. 04. 2010 Full T2-T2 interconnectivity testing
downloads to T2_CH_CSCS
Investigating some of the systematic errors
19. 04. 2010 Full T2-T2 testing. High throughput of about 10 TB/day

Tailing by one data set
Local monitoring plots
CMSSiteLog17
17. 09. 2009 lcg-cp stageout problems from CRAB jobs
lcg-cp refuses to create more than one subdirectory layer at T2_CH_CSCS - this seems intentional!
lcg-cp correctly creates multiple subdirectory layers at T2_IT_Pisa
srmcp succeeds in creating nested subdirectories at CSCS
Differences between T2_CH_CSCS and T2_IT_PISA
dcache configuration?
The behavior at CSCS is inconsistent for lcg-cp (but not for srmcp)
04. 02. 2010 Problem solved after updates to dcache 1.9.x
