Hey Ikai, thanks for the reply. Are you sure about the 90 day thing? I was reading a thread here where Nick Johnson suggested it was a fixed buffer size:
http://groups.google.com/group/google-appengine/browse_thread/thread/faa52812efdbeaaa/a22d1a02a97e95df?lnk=gst&q=appengine+logs+circular+buffer#a22d1a02a97e95df In that case, the person asking seemed to be only able to keep 20 minutes of log data before old logs started to be overwritten (a busy site I guess!). Has something changed? Could you check out what the case actually is? If I might, I'd like to request if log related 'quotas' could be exposed and published, and expandable with money if possible! :) They're quite critical to an app I'm trying to plan, and while the current setup seems to be OK for my needs, the blindness to what's happening under the covers and what might happen going forward is a wee bit disconcerting.
