Routes down to yahoo.com, etc. from Wash DC?

IS it just us out hereon the Right Coast in the Washington DC area, but are a number of routes to the Bay Area and Southern California down? We can't get traceroutes through or customer connections to www.yahoo.com, while other like www.msn.com and http://home.netscape.com come in just fine. Is it www.yahoo.com, maybe? Just wondering, as I narrowly veer close to the edge of being on-topic..... :-) Mary Grace
