Strage issue with Fastweb and SSH/GitHub

I recently changed my Internet Service Provider and suffered from a strange connectivity issue.

When connecting to SSH on Fastweb network I got some random hangs and especially on GitHub I couldn't either fetch/clone or anything.

The solution is quite strange, as found on this forum, and requires to add a flag to every connection made, -oIPQoS=cs0

However it's not possible (or I haven't found a way how) to set connection parameters for git, so I had to rename the system ssh into ssh_right and supply this simple script instead:
$ cat /usr/bin/ssh

exec ssh_right -oIPQoS=cs0 $@
