Hi Charlie, I don't remember the complicated formula WLCG uses for reliability and availability. For scheduled outage, we register the window at a OSG web server, and WLCG is supposed to take that info into account when calculating availability. However, I don't think that part of info flow (from OSG to WLCG) is fully functioning. regards, Wei Yang | [log in to unmask] | 650-926-3338(O) Young, Charles C. wrote: > Hi Wei, > > Thanks for the forwarding.
