I don't run named, so I'm not sure if some configuration issue is at play with |
| 27 |
your setup. Did you try traceroute? I am able to ping 'www.youtube.com' as |
| 28 |
well as 'youtube.com'. They resolve to different IPv4 addresses, but the same |
| 29 |
IPv6. When I run traceroute the route deviates 3 hops before the target, |
| 30 |
whether I use ICMP, or TCP on ports 80 and 443. |
| 31 |
|
| 32 |
Therefore it seems there is a URL redirect on youtube. When tested from here |
| 33 |
the redirection is not on the same webserver, but to some other server/farm |
| 34 |
hidden behind Google's vast estate and reverse proxies. The routing from your |
| 35 |
network to Google would be specific to your location. |
