Attached to Project— Hosting
Incident
all (Plan hostings)
CLOSED
100%
We had an attack on the mutu , that caused a crash of the
Load pre-balancer. We made it out of the routing and then
put it back and restarted the second load pre-balancer.
The situation is stable.

We give the bugs to a10 who sold us the Load pre-balancer
for the bugs repair.

New crash of the infra. We will recall it from production.

The attack continues.

We changed the settings to allocate less RAM and avoid
the crash due to the RAM saturation.

We are testing also a protection against the attacks
that limit to 100 packets per second and IP.
For the time being, the action is just "log"
to see what's going to happen.

We did also a protection on the spot? If an IP sends more than
200 packets per second , it is blocked during 10 seconds.
