Seeking Yahoo Network Engineer

Hi NANOG. It was suggested I try this list to contact a Yahoo Network Engineer to help me with this problem I'm seeing. I have around 200-300 of my Yahoo hosting customers experiencing this issue where http requests to their websites are timing out. For the last week, I've been trying to reach out to Yahoo Hosting for last week regarding timeouts for http requests from multiple datacenters. Can a Yahoo Network engineer contact me to assist on diagnosing this issue off list? Thanks. My email is at harrison.hung@gmail.com Thanks a bunch. Or other suggestions are welcome as to how I can escalate this issue with Yahoo. Regards, Harrison
