No. We are not shutting down our master-server.
The master-server being up or down is an issue with our VPS that will be fixed soon. Like we said many times before, we will never force anyone to move to a different platform. The “master-server” costs us almost nothing to run so you can enjoy the service as long as we can keep it up.
UPDATE#1: If anyone notices some exploits being run against the clients/servers, report them directly to me. Try to get a crash dump as well.
UPDATE#2: Security-fix release is planned for this weekend. Stay tuned!
