Some internet providers manage traffic at busy times, and video streams are a common target. Others block certain servers outright.
Signs
- Buffering mostly between 7 pm and 11 pm, fine during the day.
- Speed tests look fine, but streams stutter.
- Everything works on mobile data or a friend's connection.
- Big live events are much worse than ordinary evenings.
Test it
- In the evening, play a busy channel and note buffering.
- Switch to mobile hotspot: better? Your home connection is the problem.
- Back on home internet, connect a VPN in your country: better? Your ISP is likely throttling.

| Problem | Fix |
