Io si, per esempio www.kernel.org

Please note that kernel.org uses Explicit Congestion Notification (ECN), as
defined in RFC 3168. Some broken firewalls or gateways may have problem
connecting to ECN-enabled servers. This page has some information about how
to fix some such gateways. 

Explicit Congestion Notification (ECN) allows routers to notify
  clients about network congestion, resulting in fewer dropped packets
  and increased network performance. This option adds ECN support to
  the Linux kernel, as well as a sysctl (/proc/sys/net/ipv4/tcp_ecn)
  which allows ECN support to be disabled at runtime.

  Note that, on the Internet, there are many broken firewalls which
  refuse connections from ECN-enabled machines, and it may be a while
  before these firewalls are fixed. Until then, to access a site behind
  such a firewall (some of which are major sites, at the time of this
  writing) you will have to disable this option, either by saying N now
  or by using the sysctl. 

Non so se vale lo stesso discorso per il sito HP.

Se si, si risolve tutto con un cat 0 /proc/sys/net/ipv4/tcp_ecn, almeno
credo (qui sto andando a naso).

Ho azzeccato?
