Notice the massive drop for video services?

Fixing Buffering

1

Use Fast.com

Check your speed on Fast.com. If it's way lower than Speedtest, you are being throttled.

2

Change DNS to 1.1.1.1

Sometimes ISP routing to CDN servers is bad. Cloudflare DNS can help route better.

3

Test with VPN

If a VPN fixes the buffering, your ISP is deliberately throttling video traffic.
