      IE 11 copy/paste problem

      It has come to our attention that people using Internet Explorer 11 (IE 11) are having trouble with copy/paste to the forum. If you encounter this problem, using a different browser like Firefox or Chrome seems to get around the problem. We do not know what the problem is, but it seems to be specific to IE 11 and we are hopeful that Microsoft will eventually fix it.

Last Updated: 2007-07-06 13:48:57 UTC ~ "A couple of readers alerted us that http://www.yahoo.com appears to be down. At this point, we have no idea why or if this is at all security related. But it does indeed look like Yahoo! is down."

 

(Same observation here...)

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

Last Updated: 2007-07-08 19:15:56 UTC - "...Initially we thought that it was a problem either at Yahoo or perhaps inside Verizon's networks based on emails we received. 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."
