That's MBit, not GBit? I got personally hit by 200-300 MBit/s, at no
provocation.
I parsed that as ten 90 Mbps attacks running in parallel, adding up to
900 Mbps - that is quite sizeable (but probably still not enough to
take a country offline - we have been hit with that levels of attacks
but did manage to pull through without outages most of the time).
More often that not, the most devastating attacks fill session tables
of session-tracking firewalls far quicker than filling up bandwidth
pipes I suppose - a 1000-node botnet with each node creating 1000
sessions will fry a firewall capable of 1-million sessions. This is
probably what took individual portals offline in this case rather than
the volume of the attack.
