Apple TV agonizingly slow downloads since Dec 08-Jan 09.

Since late December I have noticed horrible download times from Apple TV movies. I am running 12,544 KB/s down with 22ms latency on DSL Reports speed tests. I have had the Apple TV for months and it usually downloads and lets me start watching a movie ( HD or regular) within 30 seconds while it continues to download. Now it is taking 8 hours on random nights. I have reset the router and cable box to no avail when I run into this problem. needless to say, it's most frustrating and not Comcasts fault as I have run extensive tests.

Anyone have info on this recent problem??

apple, Mac OS X (10.5.6)

Same here, in looking it's pulling data from a72-246-51-6.deploy.akamaitechnologies.com
however it's doing only about 60 packets a second. In the past it would do about 1200 packets a second. At 60 it's come back in 7 hours, at 1200 which it was pre january time frame (and maybe 10 or 20 seconds when starting a download) you could watch the entire movie right away.

where 192.168.1.100 is an internal firewall
24.108.24.1 is the IP assigned by the cable modem
66.163.76.217 is also owned by shaw

On a clear day google.com is 13 hops away, versus 72-246-51-6 which seems to sit right close to shaw's servers somewhere.

so it's at much as 10x long to ping google than 72.246.51.6 which
tells me the turn around time talking to 72.246.51.6 is very good.

Therefore I can only assume either akamaitechnologies.com is doing a lousy job, or the AppleTV is funky however it's not as if any software updates occurred.

Good investigative work, johnmci!

That seems to be the cuplrit -- and it's affecting anything from download speeds to the amount of time it takes to load 30 second TV Show clips.

I assumed that because Apple had recently farmed out a percentage of their network delivery chores to Limelight, that they were to blame for the bottleneck. Looks like the difficulty may lie elsewhere after all.

There's a much longer thread about this ongoing slow download problem elsewhere in the forum. Could you guys join us there? People have been pointing Apple Support to it as proof that it's a wide-spread problem so it'd be a good to have as many folks as possible that have the same problem to focus in once place. 🙂

Here's a link to that thread:

Same thing here last night. Another "will be ready to play in 8 hours" message, instead of the usual near-instantaneous "Your movie is ready to watch" message -- which is what I'd always had prior to last December.

This is rendering my Apple TV pretty much useless for renting movies. I used to be one of its biggest boosters, and have sold at least five of my friends on ATV in the past six months. It's still a great addition to my living room, but it's completely undependable when it comes to renting a movie. What a shame.
