NORDUnet operations are carried out by NUNOC in Stockholm and by the national Nordic networks.
End-users should contact their own organisation's IT support first and they in turn should contact their own respective NOCs for error reports.
NORDUnet publishes also the Open trouble tickets. Please consult the list of trouble tickets before reporting problems to see whether the problem has already been identified and handled.
The email address of the NORDUnet Network Operations Centre is 247@nordu.net. NORDUnet has an 24x7 on-call NOC support and the phone number has been published to the authorized persons. When reporting possible problems to 247@nordu.net, please make sure that it is something that should be dealt with on the NORDUnet level.
