[bitfolk] vps ping response times

Hi all, I got into a discussion with one of the people I'd recommended to bitfolk about ping times to VPSes (he was seeing some spikes). So I setup some graphs, but didn't see what I expected. Here's the graph for his vps: http://f8lure.mouselike.org/archived_graphs/baa.muuh.co.uk_day25.png which basically looks fine (which doesn't match what he was seeing from his own graphing, which is odd), and here's the graph for my VPS: http://f8lure.mouselike.org/archived_graphs/button.heenan.me.uk_day25.png The number of huge spikes (and some packet loss, shown red) on this surprised me. Would this kind of result be expected? Both graphs are for yesterday afternoon. Both vpses where pretty much idle as best we can tell. Cheers, Joseph
