Check Your Connection to Factorio Servers
See how much latency your ISP routing adds
Detecting your location...
Estimates based on real-time measurement to nearest Cloudflare edge. Actual in-game ping may differ by ~15ms due to different routing to game servers. Your IP is sent to ip-api.com for city-level location — we don't store it.
How to check your actual ping in Factorio
Press F4 to open debug options → check 'show-multiplayer-statistics' — OR press F5 to open the debug screen (shows latency while open) Small overlay in the top-left or debug screen shows latency in ticks. Multiply ticks by ~17ms to get milliseconds at normal game speed.
Debug overlay shows 'latency: 6 ticks' — at 60 UPS this equals ~100ms round-trip. The value updates live as your connection quality changes.
If your actual ping is higher than our estimate, your ISP is routing Factorio traffic through a longer path than necessary. That gap is exactly what PingAim optimizes.
