Are proxies useful for accessing educational resources?

My colleague told me about proxy server checker https://proxy-checker.net/en/ and I honestly regret not using it earlier because it’s such a time saver. I use proxies for scraping product prices across different countries, and without a checker, I often hit dead ends with slow or blocked IPs. This tool quickly filtered the bad ones and showed me which proxies could handle heavy requests. I loved how it also indicated response time in milliseconds, which is crucial for scraping tasks. Thanks to it, my scripts run smoother and with fewer interruptions.
