It might be worth pointing out that it wasn't exactly "an atlas user",
Rod is submitting jobs for atlas as a whole so you were seeing the
effect of the entire atlas production. I believe that atlas are now
re-thinking their strategy. Previously they had replicas at every site
which was running jobs, which led to many complaints about SEs being
filled up. They then switched to having only one replica at big storage
sites like Sara, but clearly that isn't acceptable either, so probably
they will now try using some intermediate number of replicas. Of course,
if the Grid had fulfilled its promise this would all be automatic ...
