DDoS & Flooding

Floods of packets, connections or requests sent from a VM.

A VM sends a flood of packets, connections or requests at someone else to knock them offline. It burns your bandwidth, gets your IP ranges blocklisted and draws abuse reports to you. Frabs measures each VM's outbound rate and limits it the moment it crosses your thresholds.
