In case others are having the same problem, I have not been able to contact any Google domain for the last 36 hours. I use Videotron as my ISP and they say the problem is with Google. Doing a tracert on an attempt to visit www.google.com shows contact with Google IPs but no communication is established. I also do not see Google Adsense ads in the Metroblog blog. Since I have changed nothing in my settings, I’m wondering whether this is a wide-spread problem.
