11:00 → 11:20 Experiment problems/issues

Review of weekly issues by experiment/VO - LHCb - CMS The only CMS issue is that Brunel showed up with a site availability < 40% which a closer look revealed was because of bad connectivity in the Phedex links *to* the T1, i.e. copies from Brunel to T1 fail. Actual jobs running at the site were not affected, so annoying that this shows up as low site readiness(*), but Raul is looking into it, to see if this is a consequence/side-effect of the recent CMS induced tuning of his DPM. (*) Difference between left and right plot. Of course Phedex problems don't trigger alarms unless CMS files a ticket, which they didn't. https://twiki.cern.ch/twiki/bin/viewauth/CMS/CompOpsMeeting#Tier_2_level Bristol still has two CMS GGUS tickets: 106554 and 106325 and RAL T1 has one: 106324. - ATLAS - Other
