red51 just an observation. We did not have problems with the ddos attacks until we added pear to pear and now since we have moved to the steam server we have this problem. can we ditch pear to pear and go back to your master server and it might stabilize everything? It is just a thought and nothing more.
Then again that could be a big mess since everybody has changed over to the uid for identification and then there are those that have changed there names. This might not be the best action either. I wish I could help red51 but I don't know how.
