I saw 31,500 posts to n.a.n-a.m at TRIUMF. Saw almost none here because our spool was full after 3,700 and by the time it came back up (cron job runs at 2200 to do the expires) the cancels had already caught up to the articles (Mind you, the cancels themselves still came through, up to 5,000/hr!) >I also know that Switch has some serious problems with capacity (only >400kb/s towards the US.. 200 ppl surfing at 2 kb/s for about 70 % of >switzerland (some private providers like EUNET have their own lines).) See http://www.switch.ch/switch/lan/ for usage stats, though from my memory of the paths in messages here, switch gets a lot of its Usenet feeds from European sites, so I'm not sure that the _3_ Mb/s link to the US is a limiting factor in Usenet propagation. Remember, the idea of Usenet is to get around difficulties like that, be they permanent, temporary, accidental, or malicious. -- Ivan Reid, Paul Scherrer Institute, CH. reid@psi.ch
