How accurate is Downdetector?

Downdetector is generally accurate for large, widespread outages by tracking spikes in user-reported issues, but it's not perfect; it can be misled by user errors (local problems, misattribution) or local ISPs appearing as global issues, and it doesn't verify why a service is down, just that many people report problems. It's a useful indicator but should be supplemented by official status pages for definitive confirmation.

There's no single "most accurate" speed test, as accuracy depends on what you're testing (streaming, general use, specific bottlenecks), but Ookla (Speedtest.net) is the most popular and comprehensive, while Cloudflare and TestMy.net are praised for objectivity and bypassing ISP manipulation, and Fast.com (Netflix) is great for streaming.
