The TTT server has had/having some serious lag over the past few days.
This is not something that just myself or a few others have experienced, everyone on the server is getting it. People are leaving the server because of how bad it is.

Just got on to check it out, and to me it seems like a DDoS attack. We've had them in the past so it's not much of a surprise. I say this because the lag is not constant, it's random and comes and goes. If the host machine was being stressed we would have near constant lag, but this is large spikes of it happening at random intervals.
