FS#33692 — DNS Anycast

Attached to Project— CDN
Maintenance
Backend / Core
CLOSED
100%
Since the attack we received on DNS Anycast at the beginning of the month (https://travaux.ovh.net/?do=details&id=33290),
we have added a rate limiting on ANY type requests.
It has helped to improve stability when under attacks but we are still seeing some latency increasement hen we receive a DNS amplification attacks.
So we plan to block all ANY requests on DNS Anycast in order improve latency in that case.
