Hi,
This is mostly just an interesting anecdote but there are also a few questions.
Hetzner informed us (see below) about an attack on our relay (not an exit). It looks like it's just normal traffic from other relays so all is good, but the switch sees incoming activity almost 3x higher than what comes in on the server's interface (90Mbit/s, 13k packets/s). If most of packets are dropped, it must affect the performance of Tor connections.
Is this because the Tor network is overwhelmed with traffic and are all relays subject to much higher requested traffic than their limits?
Thanks,
Daniel.
