(Same observation here...)

But no details or confirmations at this point. Other Yahoo services like Yahoo IM was affected as well."

Later we determined that it was not Verizon or Yahoo, but more likely an issue at Level3. Yahoo's official response is here*... Bottom line - it wasn't Yahoo having the problems. It was a BGP routing issue that affected reachability of many sites that had routes advertised through Level3. Unfortunately this is one of the Internet's "dirty little secrets" - BGP updates are the lifeblood of the Internet but yet there are many ways these route advertisements can fail. There have been many suggestions for improvement... even the US Department of Homeland Security has tried to get some traction in making improvements to the routing infrastructure**. But the Internet remains vulnerable to these types of configuration errors and intentional false routing advertisements."
