FS#19534 — GRE protocol (tunnel)
Incident Report for Network & Infrastructure
We have detected difficulties on seme equipment that seems to be overloaded. We have been investigating, but the problem increased around 11:50 p.m. without any possible explanations.
We are trying to find the reasons why we observe so much latency, and working to restore the service ASAP.

The holiday period has arrived ..

We are detecting more and more DDoS on the GRE protocol
(Which is used to make the tunnels). Few customers
use this protocol.

Given the size of DDoS (520Gbps) we have decided to mitigate
GRE traffic on the VAC by IP SRC at 100Mbps. If we
detect a DDoS, your IP will be protected and one of the
protection rules will be to limit the
traffic at 100Mbps on the GRE protocol.

If you activate VAC manually or you do not use
VAC, you will not have this limitation.
