Question / Help Massive dropped frames with YouTube Live this morning

This morning I started a live broadcast using OBS and immediately noticed something was wrong: 44% dropped frames, and when I watched my broadcast, it was basically unusable. Restarted OBS and switched to backup YouTube ingest server, no change. Reduced bitrate from 3.5Mbit/sec to 2Mbit/sec, and that lowered the dropped frame rate from 44% to 6% which my remote site said was usable.

I finished my broadcast, then did some more testing. Multiple speed tests to different locations indicated I had 6Mbit/sec available. Ping showed no significant packet loss (one packet lost over 20 minutes of ping). CPU usage was a typical 30-40%. I was connected to the network switch via a cable, not via WiFi. The problem still occurred, and went away by itself about one hour later.

Log file is attached. I see that there have been several releases of OBS since mine. I will upgrade it. In the meantime, I would still appreciate any suggestions about why this may have happened.

Note line 219:
10:35:09.252: Output 'simple_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 427 (22.3%)

Thanks. I satisfied the first three in the list. Since the problem is no longer happening, it's difficult to troubleshoot further.

On a whim I checked the YouTube Live broadcasts for big companies like Al Jazeera and Bloomberg. They too had brief skips in their broadcast. So for now I'm assuming it was a systemic YouTube issue.

Would be delighted to hear from anyone who was streaming to YouTube this morning and either had or didn't have issues.
