Yes. This hasn’t been true for a long time. OVH runs a huge network and they invested in tools to mitigate and neutralize DDoS attacks[1]. Of course an attack can still saturate your servers’ NICs but they won’t drop you anymore.
At their scale they are basically forced to handle big attacks on regular basis. The fact that they offer this protection in their basic package is what makes them a great host[2].
They don’t get a fraction of the love Cloudflare gets, but they should.
