SYN Floods from Verizon in the Midwest-Chicago area?

Wondering if anyone noticed issues with customers coming from Verizon's handoff in Chicago - 204.255.168.61? We have 
couple of customers with Verizon that seem to have been flooding us with SYN's. It seems Verizon has acknowledged this, 
but as we are not customers of VZN, we have no information about this. The SYN floods stopped around 10:20 PST on 
12/29. Had enough impact to cause a minor outage.


Thanks,
Bobin Joseph
