We are just about ready to start a new server-side GameGuard patch. This will address some server timeout issues which INCA and Indy believe are causing the bulk of the disconnect issues.
It seems to be working fine on the test server and we are hopeful that this will solve our problems.
The patch process will begin with Asura and Nirvana and then move onto Bardo. We expect this will take approximately one hour total. As always, we appreciate your patience while the servers are down for maintenance.
EDIT: Asura and Nirvana should be patched and back up now. Please let us know if you're experiencing continued or new DC issues here. Thanks. Will post when Bardo's patched and back up.
EDIT 2: Bardo's back up now, too. Again, please post here if you are still having issues or experiencing new DCs.
