Sometimes while I'm playing on a server, I get a lag spike out of nowhere. I would normally assume its the host saving or Comcast being a usual piece of stuff ISP. But starting last week when I got these spikes, they wouldn't go away. Eventually I would time out of the server, rejoin, only to find out no one else was lagging. This could be a problem with my ISP but I can't tell because the latency doesn't spike when it happens.
