okay, i'm stuck trying to figure out a real methodology here. back in like 2022, you could just run a basic ping test and the numbers meant something. now every provider's dashboard shows "ultra-fast" but your scrapers time out after two minutes. i'm getting nostalgic for when you'd just buy a list from some forum guy and it actually worked half the time. these new fancy api providers with their auto-rotating ips feel slower than my old residential pool that i manually refreshed. if you aren't tracking every connection latency with your own custom spreadsheet, you're just guessing, and that's how you get burned. warning about bad providers: they all demo with a single ip to a local server. that's not how any of this works when you're hitting 50 targets across three countries. my current method is running a script that tries 100 sequential requests thru the proxy gate and logs each failure but it's eating up hours. anyone got a simpler way that actually reflects real campaign load?
