@Cacotopos @aurynn Nothing fundamentally, though with most providers this would be significantly cheaper to recover from (typical industry pricing for traffic is $1-$5 per TB depending on datacenter and quality of connectivity), and you'd need unambiguously-illegal-DDoS levels of traffic wasting to reach amounts of money like this
(Most providers would also suspend your network connectivity or server above a certain threshold instead of automatically billing - that wouldn't prevent the attack, just reduce the level of surprise a bit)
