Please do whatever you can to make ready ... Russ, This "experiment", strikes me as both pointless and harmful. First, as was stated several times during the YVR plenary, "transition" is not a plausible objective in anything like the near future. Therefore, seeing what happens when IPv4 service is off is of extremely minimal value, especially when run in the uncontrolled environment of the IETF plenary. Moreover, it seems like it's *precisely* when you're trying to bring up a bunch of new networking stuff that you'd like to have your old, reliable network in place so that you can look stuff up, download updates, etc. Even when configuring new IPv4 systems, which I understand pretty well, I generally find that I need some backup system/network connection for this kind of thing. I would expect the situation to be far worse with IPv6, where people have far less experience. Second, the IETF network is a production network, not an experimental testbed. People rely on it to get their work done, no less so at the plenary. Breaking the network for 30-60 minutes during that period imposes an unacceptable burden on those who are trying to work. Incidentally, does this include people who aren't even in the plenary? If I'm in my room trying to do slides for Thursday am I going to just experience an outage? Finally, it is inappropriate to make a decision of this nature without seeking the consensus of the IETF. Various IPv6 eating our own dogfood experiments have been proposed on the IETF list in the past and have always met with an extremely negative exception. Given that, unilaterally making this decision seems quite premature. -Ekr P.S. I don't really understand how you envision this working. Are you thinking that people will be speaking during this period? It's hard to imagine anything more disruptive to having a plenary presentation or discussion than having everyone in the room busily focused on trying to unscrew their network. If the plenary activities merit this little attention, perhaps we should consider cancelling them entirely. Or is this just an involuntary 30-60 minute interop event? _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
