what is error 999 and how do I get on Yahoo?
346898
a few months back, a yahoo employee said in a blog that:\n\nerror 999 would be served to machines sending "excessive, anomalous, or abusive traffic".\n\nThey intend to send it in cases where it seems that a user is doing something slightly naughty, such as using up all of someone's bandwidth.\n\nBut I suppose it could also be sent to anyone who happened to be using the same ISP as someone else who had been suspected of abusing bandwidth in that way.

Yahoo's server has been having problems all morning.  Just be patient.  It seems to be back up now  though.

What does the error page say?  I can't really help w/out more information.  It could be anything from your ID/password is incorrect to the web page you are trying to log on to is having problems.

Sweety, too little information...please post the question again with more details...like what happens when you try accessing your e-mai...any error message? .. \n\nTip: try using a different server address..ie.. instead of  http://mail.yahoo.com ..use the URL http://in.mail.yahoo.com or http://mail.yahoo.ca

Error #103 The Upgrade Notification Web site is not responding. Please try again later.\n\nIf you receive this message it means that for some reason the upgrade Web site you were trying to connect to was not available. This may be because of internet traffic or technical difficulties. Try again at another time.

Well possibly because it's an old computer or Yahoo! is just having troubles these days. It's best you wait for a couple of minutes before trying again. Try also another computer. If that computer doesn't do the same it's obvious it's your computer...but if you try and it does the same, something is wrong with Yahoo!.

* Possible solution\nThis error appears to be caused by some sort of bandwidth limiting system that Yahoo has put in place on their servers. Once you have exceeded your allotted bandwidth for a specific period of time Yahoo gives you this Error 999 message and doesn't allow you to access the service. People have primarily reported receiving this error when they try to access Yahoo Mail or Yahoo Groups, but other Yahoo services may also be affected.\n\nTaken from the site below... it has lots of info on that error.
