Thereafter works on the 10G internal network
for one of our transatlantic links providers,
we have reset VAC1+VAC2 for EU and VAC3 for US/CA
rather than 3 in the same time for EU+US/CA.

We will fix this issue permanently within few days.
We have to switch the network to MTU 9216 then set
the GRE tunnels instead of direct links.
Then at the end of year, we are going to have 4x10G
between LDN and BHS passing by Newark,NJ.
We will have a full internal network security and
we could re-pass in direct link.

Update(s):

The maintenance on the 10G transat is done.
We have reset the configuration on the 3 VAC
meanwhile.
