Yahoo! may just have flagged your IP as using automated queries and has temporarily blocked your use of their search.
I know this problem very well even its appearing from last 3 months . Basically what is the funda with this when some people try to search more and more and yahoo then yahoo get disconnected for sometime and it give this error because the program of yahoo thinks that its a spam or virus who is searching on yahoo . So thats why this problem occurs i have faces this problem many time like if you are using any software to generate the rankign reports then this problem certainly occurs ... so dont take bother from this problem your yahoo will be working after some time . Or you should contatc your Service Provider or administrator....
It means you were using yahoo too much. And Yahoo has temporary blocked you to access their services.
Yes automatic queries are one big reason for this. If too many queries are generated from a specific IP .. the ip gets 999 error sometime.
