I have a customer reporting the same thing. The traffic flood goes to
offline modem bank IPs. So far, Akamai hasn't actually grasped what the
problem is and says everything is fine. :(
Luckily, most of the traffic (not all) is coming from my local cluster,
so it's easier to monitor what's going on. Packet captures have shown
the same packet being sent over and over, usually over 1400 bytes in
size. Different floods may have different packets, but within a flood
it's identical. I wouldn't think you'd have data prior to the 3-way, so
I'm curious how the 3-way is being completed for the data to be sent.

I appreciate everyone's assistance.

I'm looking for an Akamai contact to try and address a strange
situation.
We have multiple sites across the country that aggregate 56k dialup
customers. Different sites are randomly experiencing inbound traffic
spikes that are overwhelming the uplinks to our carriers, causing DoS
situations. These spikes far exceed the bandwidth that could
possibly be used by the number of dialup customers connected. We've
been able to trace the source of the traffic to Akamai boxes, but so
far have been unable to reach anyone at Akamai to discuss the
situation. We're attempting to get payload information, but the
traffic volume is making it slow going setting up packet captures at
these sites remotely.
Thanks in advance,
Tom
