As many of you are aware, there are a number of problems with partychat right now; ranging from bots appearing offline to missing messages.
A few of us are trying diagnose what the underlying issues are. In general, these sorts of problems seem to stem from our connection to Google Talk servers which we have very little control over. Hopefully we'll get everything sorted out and fixed to the best of our ability soon.
Thanks to everyone who's been reporting problems -- it's touching to hear how many different people around the world are using partychat (and I share your frustration with how much of a disruption to your life it is when it's not working properly).
