Angry with Verizon
I've noticed this the last few days and it is most frequently the result of Verizon's own DNS server errors.
For example, I typed »www.google.com and got this message. It only happens about 1 in 50 pages I load but that's too much. I also had this problem at www.linuxquestions.org. I was replying to a post and then when I hit "post message" I got the redirect. After using the back button I tried to post again, and again got the redirect. The only way to fix it was to close Firefox and then restart Firefox, which caused me to lose a long message I had typed.
Upon further investigation I found that verizon was placing cookies to track the failed addresses. To see this for yourself, open firefox, go to Edit->Preferences->Privacy->Cookies (or Tools->Options->Privacy->Cookies) and view the cookies from verizon. Type an erroneous address such as www.verizon.cmo and you will se the cookie appear.
I followed instruction at verizon website to opt out but I'm still getting these redirects.
Let me be clear on this: I HATE IT. ABOUT 90% OF THE TIME I GET THE REDIRECT IS BECAUSE OF VERIZON DNS ERROR, not my mis-spelling or bad address. Most times I've typed or clicked a good address that inexplicably did not resolve.
