Trying to contact MSN/hotmail/microsoft admin

All,

Sorry to post this on-list but I am trying to reach anyone that works for or has a contact at the MSN/Hotmail NOC. We have been trying all week to reach someone. Currently a customer (Cable MSO) of ours has a few /24's being dropped at the entry point to that network.

If someone could please contact me off-list I would be very grateful.

Thanks
