There’s nothing wrong with roadrunner, especially not their business connections.
Best thing I can tell you is that if you aren’t being kicked stay and play. Admins are allowed to kick you if you are extremely laggy.
There’s no way for the server to detect or compensate for sudden spikes that desync you from the server. Ordinarily you get kicked when this happens but if it seems to be happening alot then call your ISP or landlord and have them deal with it.
