Here's another hint: when stuff scrolls off the CB, check last hour of cb (which was suggested multiple times in the CB) or the link at cb60 (currently http://mini-cb60.datenzoo.de/, but it has changed at least once). The former updates every 5 minutes (if there is any activity), but can go back more than an hour. The latter is more dynamic, but I think stuff scrolls off after an hour no matter what. It's too late now, but keep it in mind for next time. You may want to bookmark one or both of these links so you don't lose them.
