Ping doesn't really tell much to be honest and way too many people depend on ping and assume the lower the better, yet it doesn't actually matter to be honest. What actually matters most of the time is the network itself, if the network is being choked or is utter shit you're going to have packet loss no matter if your 30 ping or 300.

The only possible thing if only a certain amount of players are lagging check to see if it's a certain region and than if that is the case it could be a network backbone that could be experiencing problems, a good way to figure this out is to contact your provider and provide trace-route and ping/packet loss examples so that they can figure out which backbone might be causing the problem.

The next possible thing is the network is just a piece of crap and doesn't have any real backbones, so the person is attempting the connection directly with no help (normally what happens with home hosted servers, as home ISPs normally don't provide a network with backbones) this means you need to find a new provider and try to find one that actually has a network with Tier 1 network backbones such as Level3 and such.

Now this is all if only certain people are lagging that are in a certain region or far from the server.
