The ACE is now rebooting


Comment by OVH - Wednesday, 30 April 2014, 17:52PM

We tested a lot of things and it seems the
problem is coming from the ACE in Frankfurt.
We opened the TAC support and we're checking with
Cisco to see if the ACE is broken or we have a
bug.

we removed the IP that is DDoS's from CDN to Mutu.
CDN works fine now.
Mutu has no problem to manage the DDoS.

It's a L7 DDoS with the true requests to 1 URL.
The origine of the DDoS: Russia.
