 	Hi all. Just so you guys are aware of it, we enjoy a peering 
arrangement with YouTube and Google, as well as Akamai and Limelight 
content distribution networks and Microsoft. We get this as a benefit of 
membership with ACORN-NS, the Atlantic Organization of Research Networks.

 	What this means in practice is that there are no limits on the 
traffic between us and these providers; all traffic between us and them is 
like it were running on a local network. In other words the best possible 
network connection we could have. Literally we are linked by fibre optics 
from the Chase Building to the Killam Library basement where these 
services are distributed locally.

 	With reference to the recent user letter about the slowness of 
YouTube, this user makes excellent connections to Chebucto (50K+) so 
conditions are as good as it is possible to make them from our side of 
things. Another issue could be about the resolution of the videos, where 
higher rez vids are significantly larger file sizes and require a newer 
video card and processor to render without glitching even when the 
complete file has been downloaded. Until very recently onboard video cards 
built-in to the motherboard were not powerful enough to render 720p or 
1080p without pauses or audio de-synching.

 	It's been my experience that the playback program is important on 
low-end boxes too. I've found that VLC offers the best video playback on 
low-end machines due to their superior codecs.
