VAC is currently installed on RBX, SBG and BHS. It protects DCs of RBX, SBG, GRA and BHS through a private internal network that connects these four major zones of DCs.

To complete the anti-DDoS VAC service and offer it on all our POPs worldwide, we will change the backbone MTU.
This will allow us to mount the tunnels GRE between the 3 VAC and:

- Housing GSW,FR
- Housing DC1,FR
- mPCC Paris,FR
- mPCC Frankfurt,DE
- mPCC Madrid,ES
- mPCC Milano,IT
- mPCC Newark,NJ
- mPCC Dallas,TX
- mPCC Chicago,IL
- mPCC San Jose,CA

There is no failure expected: we will change the MTU of each link one by one and as there are always several in parallel operation, traffic flows through the following link.
