The attack goes on , but the situation is stabilized.

We have an attack type slowloris on an IP of the
shared hosting. The atteck comes from alsmost
60000 IP which do real connections on the attacked
site and try to open the maximum of connections.


We limited the number of simultaneours connection
by IP to 10 so that the attack maintains at 600'000
simultaneours connections.

It's running correctly.

We changed the A record of the attacked site to 127.0.0.1 .
It does not change the situation for the time being.
The attack goes on but does not disturb the working
of the other sites.
