This is an update regarding issues on the free shell server.
Free shell server has experienced a attack on it's network infrastructure. The whole infrastructure is in strict mitigation mode to prevent any future attacks. While the attack is on-going, you may notice a connection lag, which may manifest in slower request->response between you and shell. Even though there is filter in place, you are able to login and use the shell as usual.
This is a short-term half-outage as all services (bouncers/eggdrops etc..) and processes are still working without any issues. You can verify your bouncers on IRC networks and see them as active.
