Very interesting Simon, and http://gtf.org/garzik/ecn/ seems to explain the
issue and name and shame the main culprits, you're right, it may be
worthwhile sending a quick email note to the webmaster, as it does mainly
appear to be a difficulty with firewalls (especially the Cisco Pix which is
common, and a fix is available for them to install).
Unfortunately it will not be 'good for your browsing experience' until both
ends are ECN capable, routers use algorithms that predict queue overflow and
bother to notify of impending congestion, and finally as the ietf draft
says, that dropped packets due to congestion should become infrequent, only
when most end systems support this, so that will be a very, very long time.
I wonder with this, how you'll be able to diagnose swamped links, many hops
away, as at present the dropping of packets is the give away. I suppose
some clever variant of traceroute, might be able to finger who's setting the
bits.
