This sounds very much like an MTU issue. Perhaps something with path
MTU discovery changed? I would try disabling it (echo 1 >
/proc/net/sys/ipv4/ip_no_pmtu_disc, I believe) or lowering your
interface MTU (ifconfig eth0 mtu 1400). This causes TCP to advertise a
lower mss.

I did try verifying the MTU path to www.usenix.org, and it's clean
until the handoff from MCI.

In your traffic dumps, were the MSS's advertised with FC1 and FC2 the same?
