A couple of my games disappeared over the week-end (mostly terminated developer games) so I went to the ticker to look for messages/eliminations etc. and I have nothing prior to August 5th @ 19:31:55 (Eastern).

I'm not seeing an option to look back further in the ticker history.

The caching daemon died on Monday and had to be restarted. Any ticker entries prior to that would have been lost when it died - they aren't permanently stored anywhere.
