Just to add another complication, this site always works fast for me at home (ADSL, probably somewhere around 1mbps - offically 750, dialup says 2 meg, performace can be anywhere between), but is always slow at work (200mbps cable). The vast majority of sites are much quicker for me at work. This isn't a recent thing , but seems to be a feature of renderosity. No other sites play up like this Tracert is hitting timeouts at my end, so perhaps the network settings are causing problems with Rendo?
