If memory serves, I think we had something like 20-30 proxy servers and I think, at the end, we had w21 through w112 for app servers, so something like 92 app servers. I don't remember how many search boxes though.

And secondly, thanks for teaching me all the stuff you did, I feel pretty lucky to have worked with you there. ------------ Brian Nilsen [EMAIL PROTECTED] On Fri, 19 Oct 2001, Perrin Harkins wrote: > > What I'd love to see is the avg spec and numbers of machines in each > > section.
