Interesting, yesterday I moved to a local caching DNS server (much faster and more reliable than what isp provided), however I forgot to set it to run at start up, first thing I do today is try to get to my gmail account, everything is working ok then I try to enter another site, dns lookup error, then I remembered I had named turned off, which means that chrome may have hardcoded google sites ip addresses or is caching them (which is less probable the other site didn't work).
