Why is my ping so high?

It’s either because the path is long and/or congested. If your ping is high across all destinations, it is likely a geographic or last-mile issue. If you are seeing high ping to one game but not others, it is likely a problem with the route traffic takes to the server, and possibly with the server itself.

No. There is always some delay between two machines, regardless of the distance between them. A figure of zero is either rounded or it was measured on a local hop.

No. For an MMO like World of Warcraft, this ping is practically very good, because the global cooldown for most abilities is way above 20ms.

Is 100 ping bad for FPS?

Yes, because it starts to affect how you aim between shots, and your character movement will start to disagree with what the server finally confirms for you.

Does a VPN lower ping?

A VPN could reduce your ping if the VPN tunnel to your game servers is shorter than the path your ISP uses. In most cases, a VPN adds an extra hop, which increases your ping. Measure world latency with the tunnel off and on, run an MTR both ways to the same destination, and compare the medians.

Does more bandwidth reduce ping?

In short, having more bandwidth than you need for online gaming will not reduce your ping in any way. It will only help in cases of a saturated link.

What is the difference between home latency and world latency in World of Warcraft?

Home latency is how long it takes for information to travel to and from the realm server: chat, auction house listings, guild information. World latency is how long it takes for information to travel for combat with NPCs and for creatures and objects around you. If your home latency is stable but your world latency is rising, the problem isn’t your home connection.
