Thumbs down. If you want to watch youtube, get out and fight GEMA, don't go and abuse free services.
Thats a riot, thanks for the laughs.
If 100.000 teenagers decide to test it (obviously not all of them concurrently), then yes, it will possibly come to the point where it isn't justified for HE to keep the service up.
It doesn't need to bring their network down, it is enough to cost them more than what they get in return.
Since the youtube pages mentioned are permanently banned from Germany, this could be a pretty sustainable spike.
I'm not sure how much traffic that represents in total?
The tunnelbroker service is for more than just system testing. It's meant to provide usable and stable IPv6 connectivity for people who don't have native IPv6. I've even hosted servers on it (nothing mission-critical though).
You have a point that HE is not going to want to maintain it if it starts costing them too much, but note that they have a very vast global network (both IPv4 and IPv6) and can reach most of the Internet without paying for transit.
One effective way around this, at least for those using VPNs in China, is to create a set of static routes forcing your in-country connections to go directly. This python program gets a list of China IP ranges from APNIC, and creates a shell script with a list of route commands: https://github.com/jimmyxu/chnroute
This was 6-12 months ago by the way. I imagine they might have tightened security since, with the party congress and all that.
