I'm in Chicago and I saw mine going to Miami as well (per rDNS). Haven't looked into it at all.

I did see a video where they said they occasionally purposely give people less than ideal facilities to test connectivity. Maybe that process buggered up?

Does anybody have a contact I could use at Facebook to get a routing issue

Some of our networks are being routed to Miami, rather than using the much
closer PoP of Sydney, and it's obviously causing significant performance
issues when browsing Facebook.
