RIPE 63, Vienna
by Rob Evans 16 Sep '11

16 Sep '11

Hi, Time marches on, and soon enough we will be at yet another RIPE meeting, this time in, according to The Economist, 2011's second most liveable city in the world, Vienna (I don't believe we'll be meeting in Melbourne any time soon, so this will have to do). Registration for the meeting is now open, and can be found along with lots of other lovely information at the meeting website: <http://ripe63.ripe.net/> Our working group is currently scheduled to meet on Wednesday afternoon, but be aware that until the meeting plan is finalised, that could change to any other point between Wednesday and Friday. If you'd like to present something to the working group, please drop Joao and myself a message at <routing-wg-chairs(a)ripe.net>. If you have some plenary content you'd like to present, then we have instigated a programme committee for RIPE 63, you can find the details at the following location: <http://ripe63.ripe.net/programme/submit-a-topic/> See you in Vienna! Rob
