Large volumetric flood targeting Frankfurt scrubbing edge
- Frankfurt scrubbing edge
- Layer 3/4 filtering
- GRE tunnel termination
Updates
- Resolved
Attack traffic has subsided. Frankfurt scrubbing, Layer 3/4 filtering, and GRE termination are operating normally.
- Monitoring
Additional scrubbing capacity and tighter Layer 3/4 filters were applied. Customer tunnels are recovering; monitoring residual attack traffic.
- Identified
Confirmed a multi-vector Layer 3/4 volumetric attack exceeding usual baselines toward several announced customer prefixes.
- Investigating
We are investigating increased drop rates and GRE path instability at the Frankfurt scrubbing edge.
