YEs- it's all over the internet. If you go here:
http://www.freerepublic.com/focus/f-news/1497077/posts
and read the last 50-75 posts you'll find some pertinent info. I was thinking (hint-hint) that one of our geeks might start a thread for this...it's pretty important.
Being a non-geek I can only gather that Roadrunner is having some issues with Cogent and Leavel 3...that have yet to be worked out- this is the result.
ooops- that's Level 3.
I believe Roadrunner is on a Level3 network... so if blogspot.com is on Cogent, you won't be able to get from one to the other without routing through a third party.
>>> with Cogent and Level 3
The issue is between the two of them.
