I lived for years limited to similar speeds, you are hilariously wrong. That's 240p YouTube, most of the time. Sometimes it won't load 240. Most downloads through a browser will fail outright. You can download something, have that download saturate your entire internet and knock you offline. Anything autoplaying is aids. If someone messages you a link with a thumbnail you've just been DoSd, not DDoS because it only takes one person to kick you offline.
