Ping and lag in South Dakota
From Sioux Falls, the closest major cloud region is Ohio. A good wired line usually sees about 26 ms there, and no connection can go below about 12 ms. In games that ask, the Central servers are usually the ones to pick, and a game's own data centres may be closer still.
Estimated ping from South Dakota to US server regions
Typical ping on a good wired cable or fibre line, in milliseconds. Most online games, voice chat and video calls run in these cloud regions or next to them. Wi-Fi and a busy line add to these numbers.
| From | Virginia | Ohio | California | Oregon | Montréal |
|---|---|---|---|---|---|
| Sioux Falls | 33 ms | 26 ms | 41 ms | 35 ms | 36 ms |
| Rapid City | 41 ms | 34 ms | 34 ms | 28 ms | 43 ms |
| Pierre | 38 ms | 31 ms | 37 ms | 31 ms | 40 ms |
South Dakota is wide enough that the best region changes: from Rapid City it's Oregon (about 28 ms), not Ohio. Pick by the ping the game shows, not the region name.
Test your real ping from South Dakota
Measured from this browser to the same regions. Close to the table means your line is healthy; 40 ms or more to Ohio means something is adding lag, and the Lag Check finds what.
Ping to game and call servers
Round trips to the cloud regions where most game, voice and video servers run. Distance sets a floor on your ping that no setting at home can lower, so pick the closest region when a game lets you.
Where lag in South Dakota comes from
In your home
Weak Wi-Fi, a busy device and background downloads add the most lag. Try a cable, then check each room.
Check Wi-Fi in each roomOn your line
When someone uploads or streams, a queue builds in the router and your game waits behind it. Smart Queue on the router fixes it.
Fix bufferbloatBeyond your line
Distance sets the floor in the table above. A route that runs well over it is a detour your provider takes.

What is a good ping for gaming in South Dakota?
From Sioux Falls, a good wired connection usually sees about 26 ms to the nearest major cloud region (Ohio). Anything under 40 ms there is fine for fast online games. If you see a lot more, something on the way is adding lag, most often Wi-Fi or a busy line (bufferbloat), not distance.
Which server region should I pick in South Dakota?
Usually the Central option. The nearest cloud region to Sioux Falls is Ohio, but from Rapid City it's Oregon. When a game shows the ping to each region, pick the lowest number rather than the closest name.
Why is my ping high in South Dakota when my speed test is fine?
A speed test measures how much data fits through your line, not how long each packet waits. Ping goes up when Wi-Fi is weak, when someone else uploads or streams and fills the router's queue, or when your provider routes traffic the long way round. A Lag Check finds which one it is.

How we estimate: light in fibre covers about 200 km per millisecond, a normal route runs about 1.5 times the straight line, and a good home line adds about 8 ms. Region locations are approximate and games may use other data centres nearby. Updated 2026-10-30.
