The DNS and the peering have nothing to do with it. It's YouTube screwing around with their website, servers and infrastructure. The majority of the issues started when they released their site's redesign. It's not just Telus and it's not just Canada having this issue. Unless you can get Google to fix their servers, expect more of the same. See > »www.google.ca/search?q=slow+youtube
I know it's not the peering... I was joking as if it was the peering maybe Telus would fix it then.
