If it helps anyone to improve connectivity/performance, 59.1020 (IAD2) is
in a data center in Ashburn VA with good connectivity and some existing
HECnet links today. Happy to add more links if it helps.

One "hack" is to configure all routers in an area "L2" and the
end systems (stubs) "L1" routers. And then try to full mesh the
Area routers.
