This week we have been decommissioning the iLIGO H1 systems in the MSR and control room. The iligo DAQ is now powered down, all legacy VE, FMCS and slow PEM have been transitioned to the new H2 DAQ. All but the legacy computers and networking gear have been removed from the MSR (see photo). The archival iLIGO services (ilog, blue, wiki) are being relocated to the LDAS server rooom and will run in read-only mode to support S6 and squeezer data analysis.
