I'm watching some extended HD YouTube videos on my Apple TV tonight without any drops or buffering at all.

Hey Dan, I didn't see your PM until now. I didn't get to test Youtube in the past two days. I'll try to get some data in the next few days and I'll reply to your PM.

But something I did seem to notice and just by looking at some of the times posted in the thread here and over at DSLreports is it seems to happen during primetime for the East Coast. Once it hits midnight over there (9PM our time), everything seems to be fine.

I didn't see Dan's PM until now. I'll now be logging, youtube's stats for nerds when I encounter the throttling.

I would note I saw this Thursday and Friday both at 8PM (PST).

While it could be a benign AT&T caching issue, the timing of it brought to mind mind an Ars Technica article from 2013, Why YouTube buffers: The secret deals that make—and break—online video. Being a long-time Sonic customer, I hadn't been in a position to see such shenanigans until my recent switch to FTTN.

When I first got FTTN I noticed a lot of issues and when I changed from AT&T's DNS servers to OpenDNS's, all the slow loading and buffering problems went away.

When I was first switching to FTTN, I too noticed symptoms of DNS overload with AT&T's and quickly dropped them in favor of Google-DNS & OpenDNS.

Rationally DNS servers are not a problem with these youtube buffering issues. I have been running Google DNS as my primary DNS while hitting YouTube throttling.

You don't hit DNS while watching a video. What's likely happening is that the DNS you were originally using has the edge cache locations misconfigured. Selecting a different DNS would not give you the correct edge cache but it could be a lot better than the wrong cache you were getting before.

If you are having edge cache problems, the companies managing those caches would like to know. It's their business to make sure that customers don't see heavy traffic slowdowns.

These are my observations with AT&T's FTTN network:

1) as another user found, AT&T's overseas network connections are iffy. I've observed slow speeds to servers in Europe.

2) using a VPN (I've been using the IPSec, since the OpenVPN beta is flakey for me; though the former isn't perfect either) usually provides relief

3) I switched away from AT&T's DNS from the start. It is not the issue. I've had to resort to OpenDNS and Google, which are ok, but would prefer to use Sonic's. However, switching the VPN on and off can make that option problematic, though I suppose I could use one off- and one on-network entry as my router only allows two.

The bottom line is that I think we've all been spoiled by Sonic's network. I don't think there's much that can be done with AT&T's so I would hope that Sonic at least considers making their own services more friendly to those who have, or will, transition to FTTN and are stuck with AT&T's clogged pipes.

Whether that means beefing up and finishing the VPNs, or making services such as the DNS and usenet servers better accessible and more secure for FTTN users, or both, some mitigation of these issues would be appreciated.

Don't get me wrong, going from DSL to FTTN speeds is great, but going from a Prius to a Porsche is a lot less satisfying if it's limited to 55mph.

Maybe the cache servers are being overloaded during prime hours since some people mentioned it goes away after certain hours. Can anyone post the ip addresses of the servers when they do the comparison of the good vs bad? This might help troubleshooting to see if DNS is handing out non-optimal ip or if it is a youtube or AT&T problem.

I get the same result whether I use the AT&T DNS servers or the Google DNS servers. It really doesn't seem like that's the problem.

Haven't had any issues with Youtube last night. Wonder if they have corrected it or made it not as noticeable.
