Frankfurt was physically closer, so I routed the next @OpenGradient inference batch there.
​Almost immediately, three requests crossed the retry threshold and died.
​My initial reaction was the usual troubleshooting checklist: check the timeout settings, look at the queue pressure, maybe a bad model release? But then a much more distant node started clearing the exact same workload without a single hiccup.

​Haversine formulas are great for measuring a straight line on a map, but they don't see what happens under the hood. They don't show your traffic hitting a congested internet exchange, switching carriers, and stalling out right at a regional routing boundary. Meanwhile, the longer physical path stayed on a single backbone and cleared the inference cleanly.
​But here’s the real kicker: the problem wasn't just getting the request to the node.
​The Frankfurt node accepted the data fast enough, but the verification acknowledgments came back completely scrambled and uneven. The app got fast inference but delayed trust signals, causing it to panic and retry tasks that hadn't even failed. It created a massive loop of duplicate execution and settlement noise.
​This proves that node placement on @OpenGradient is way deeper than just placing capacity near demand. A close node on a map can still break your application if the network path is unstable.
​I’m not throwing out distance metrics entirely—that would be an overreaction. But I’m absolutely done letting them have the final say.

Which metric should guide OpenGradient node selection when latency becomes unpredictable?
