Rumble Fighter has been peer to peer for over 10 years, and all the network settings were tuned for that. A sudden change to peer to server may be the issue if the synchronization isn't set properly. Your computer must now go through the server, so this is an additional step in the middle that may not have been coded for originally in the year 2007. There's also a language barrier, where the Korean programmer may need a translator for English. Players are teleporting, and kick combos are not fully connecting. Is it possible to change it back to the way it was?
Service interruptions are due to sustained and continued DDoS attacks on the servers. We are looking for new methods to try and block all DDoS attacks, however it has proven to be extremely difficult. Once the DDoS attack issues are resolved, the game should return to normal or at better latency than before. Our servers are still being DDoS attacked.
