The operational procedures in the NDGF infrastructure is illustrated in the figure. Any problems encountered with the infrastructure will be reported to either the operator on duty, who is reachable in normal office hours or to the NDGF 24x7 first line support at the NORDUnet NOC in Stockholm. Contact can be made either via a phone or mail, depending on the severity of the problem. If the problem can be solved immediately by the first line support by following standard procedures for bringing service back to normal a problem report is sent to the operator on duty for later problem tracing and added to the problem log. If the problem cannot be solved immediately, or it occurs in office hours it is up to the operator on duty to take appropriate action on the problem e.g.\ by forwarding it to the involved site or application expert or by taking actions on is own.
