The downtime can be caused by (1) an infrastructure/VOVirtual Organization;/VREVirtual Research Environment. upgrade or (2) the unavailability of nodes (check below). In this second case, different procedures apply whether the unavailability affects gCube nodes, gLite nodes or Hadoop nodes. In any case, the Infrastructure Manager, VO Manager or VRE Manager must analyse the impact of the nodes unavailability and declare the appropriate downtime.

Information about all declared scheduled downtimes is gathered here.

gCube Nodes
