Siege has short firefight windows, so latency, variance, and loss matter. However, one death behind cover is not enough to identify the cause.
Run the Rainbow Six Siege ping test to shortlist stable directions. PartyPing probes are not Ubisoft game servers and cannot force the facility used by your next match. Record the in-game data-center code, ping, connection icons, and whether the problem affects one match or every match.
Ubisoft previously described values below 110 ms as acceptable before additional high-ping checks apply. That is a service-policy boundary, not a claim that 109 ms is ideal. PartyPing uses 110 ms only as an official outer anchor; its S-to-D competitive grades remain engineering guidance.
US Central, Hong Kong, Middle East, and South Africa remain unsupported where PartyPing has no matching probe. Nearby names do not justify substituting another continent or city.
