      Service Interventions during LHC Technical Stop 10m
      • PIC
        I will not be able to connect to the next T1SCM, so this is just to remind that at PIC we are planning an Scheduled Intervention next Tuesday the 20th July, during the LHC technical stop days. Several interventions are planned. Most of them are related to firmware and OS upgrades affecting the Storage, Computing and Oracle (3D, FTS, LFC) services. The whole site will be declared hence in SD from 6 am until 6 pm on that day. Batch queues and FTS channels will be drained accordingly.
