I have this weird problem where sometimes I dont have access to google.com on my home computers. this include most of the google sites - maps, calendar, docs. I sometimes get a plain error page, sometimes even a weird Yahoo! error page (weird i know, especially as i am never using yahoo).
This problem happens every now and then, a few times a day for anywhere between 1 min to an hour. It happens both on the Wi-Fi network and when connecting with a wire to the modem.
What can cause this problem? It's so frustrating...Thanks!
