Maybe it's just my suspicious mind but haven't you noticed a lot of funny stuff going on recently, and I don't just mean VM related issues, but with the internet in general.
Lots of what appear to be routing issues, capacity issues, slow web page loading across multiple isp's.
mine looks ok
but some sites are taking a while to resolve for me like
www.speedtest.net and can sometimes fail to load fully at all.
Could it be anything to do with ipv6 ?
