Looks like it refers to "Mahogany Row" an alias for the 7th Floor. Digging around looks like this has been discussed before.

And also some interesting info here from someone called FBI anon:

Good info to help fill in the gaps for those of us who hadn't already come across it.
I spotted a claim somewhere in there that the 7th floor covers up trafficking. The phone number links back to a SOS directory for references to "Senior Watch Officer" and "The Watch" - Q mentioned "watchers will now erase from web." Jan 7 Q mentions "7th floor no more."
