We've been streaming Sunday Morning services to Youtube for years on Comcast. Switched to AT&T in March. And........ increasingly were having Youtube abort the stream. We were sending 60fps video, which amounted to about 6mbps; this is on a 20mbps Fiber connection. We dropped that to 30fps video, which is about 3.5mbps. I ran the Speedtest CLI every 5 minutes from a script for several 24 hour periods, and found Max Upload Latency all over the highway, from 5ms to 528ms. (BTW, we understand the upload SLA to be 37ms) Granted, the Speedtest test tries to shove 20mbps upload; whereas we are trying to get consistent 3.5mbps. this is to an AT&T Speedtest host in Atlanta. I'm getting close to nowhere arguing with AT&T. I recently took the church completely offline, disconnected our Unifi router, connected directly to the AT&T Calex box, ran the same tests, had roughly the same results. AT&T level 2 support is asking ME to tell THEM where in the hops from us to THEM that THEY are bottlenecked. Kinda hard, since MTR or TraceRoute gets 2 hops in, and then it's just stars with no data. 'cause their equipment isn't replying to me. Anyone have ideas, either on troubleshooting, or finding anyone within AT&T that actually knows anything about testing their own equipment? I was wondering about iPerf3, if they had a server for it. It would be better to test a realistic 4mbps upload. Anyone know the process to file a formal request for a failed SLA credit with AT&T? The minimal docs I have apparently are no longer correct? regards, Neal --=_766c405b685bbb998e2f03844f79ea3b Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=UTF-8 <html><head><meta http-equiv=3D"Content-Type" content=3D"text/html; charset= =3DUTF-8" /></head><body style=3D'font-size: 10pt; font-family: Verdana,Gen= eva,sans-serif'> <p>We've been chasing AT&T on streaming upload failures on a Business F= iber setup for about 6 weeks now. </p> <p>We've been streaming Sunday Morning services to Youtube for years on Com= cast. </p> <p>Switched to AT&T in March.
