          Report from France:

          Report from Italy:
          List of unresponsive sites (First Ops meeting):
          1. SITE NAME: ru-Moscow-GCRAS-LCG2
          2. ROC NAME: ROC_Russia
          3. GGUS TICKET NUMBER: #45457, #45039, #44739
          4. Reason for escalation: as reported at https://twiki.cern.ch/twiki/bin/view/EGEE/EGEEROperationalProcedures#7_6_Suspending_a_site, the ROC must suspend one of their sites if a site is in downtime for more than one month. The site is almost in SD (at risk) from 2008-12-24 (https://goc.gridops.org/downtime/list?id=15555346) and the last SD ends on 2009-04-16 (https://goc.gridops.org/downtime/list?id=20105380).
            Also, GGUS tickets are also not updated in timely manner.
          Problems Encounteredduring shift:
          1. Some temporary problems with cod dashboard on 24th of March due to the GOCDB outage.
          2. Because of GGUS update on 25th of March, cod dasboard has been unavailable for a couple of hours.

        • <big> Update of CERN VOMS server certificate </big>
          The certificate of the VOMS server lcg-voms.cern.ch will be replaced on the 31st of March. By that date all the sites should have updated their services to the version of lcg-vomscerts deployed with gLite3.1 Update42
          ( https://cic.gridops.org/index.php?section=roc&page=broadcastretrieval&step=2&typeb=C&idbroadcast=39901 ).
        • <big> Retirement of gLite 3.0 </big>
          As previously announced, it is planned that all remaining gLite 3.0 services will be retired by the end of April. At this point, all support for these services will cease.
          All sites should ensure that they are running up-to-date versions of their services.
          If any site sees a need to keep a gLite 3.0 service in the middleware stack, please submit a GGUS ticket as soon as possible.

          OSG
          • Exactly this was discussed for the last 2 weeks and Rob had an action to check. GGUS #46647: The ticket is now assigned to Rob. The action required is in the 2009-03-24 by MariaDZ.
          • Comment today in stalled urgent ATLAS ticket since 2009-03-09 GGUS #46988:
            Tim and other OSG colleagues,
            my understanding from https://savannah.cern.ch/support/index.php?107511#comment3 is that
            had you chosen status 'customer' in OIM, 
            the ggus ticket would have gone to status 'waiting for reply' and the submitter would have been prompted 
            to react. Please do so now.
            yours
            maria
