Hello Chris,
This 1Gbps link is to the IPIP gateway system in San Diego right? If so,
even if you get a faster pipe, can this gateway server (I want to say
this is a FreeBSD machine right?) actually forward at those rates?

There has been a plan in place to upgrade the link to
10Gb/s for nearly a year, there were two attempts at upgrading which failed due to the new
link not working, but UCSD have now identified the issue and the upgrade has been
expedited and, all being well, it will be upgraded within the next week or two.
Of course that just means the next DDOS will be hitting the gateway much harder, but at
least we will have some decent headroom under normal circumstances.

I agree with Rob! Normally you should start upgrading the connection if the
average reaches 50% of it's capacity

https://mailman.ampr.org/mailman/listinfo/44net Yes it would be worthwile to research (with the
IP address as information)
what could
be the reason behind this. Assuming it was not 44.0.0.1 but some
amateur's IP, it could
be some retaliation against that person and they may be able to identify a
likely source
and legal action may be possible.
Aside from that, I think there is too little headroom on this connection
and it needs
to be upgraded to 10Gbit or some teamed 1Gbit links when that is more
practical.
The background noise already takes up 650Mbit/s of the 1Gbit/s available...

https://mailman.ampr.org/mailman/listinfo/44net Tnx. Chris for the update.
I'm still wondering what the goal of such an attack is...
