  6. Conclusions this week • Our current practice, i.e. notifying one of the 2 sites involved in a case of network problem, is correct. • The issue is who feels responsible for finding a solution to network problems between sites. • A network ‘authority’ should be involved in all relevant tickets, no matter which physical infrastructure is used. • There is a GGUS Support Unit NetworkOperations but seems in-effective in its current ‘incarnation’. No traffic and no WLCG supporter involved. Details in savannah support #115213. Dimou M.
