[outages] load

[Nick Olsen]

Saw this today. Customer's interface was a vertical line straight to their 
200Mb/s rate limit. Had their Equipment wheezing.
  
 Traffic coming from 38.29.169.65 and 38.29.169.75, Appear to be Akamai 
devices inside AS174 (Cogent, Who is one of my transit providers). TCP/80.
  
 Customers NOC is looking into if the traffic was legitimate or not. Being 
that I came from Akamai, I like to think that it is.
  
 Ratelimited to 50Mb/s at customer request. Even at my core, I've got 
200Mb/s coming in on the flow, And I'm dumping all but 50Mb/s of it. It's 
performing like UDP.

 Speculating...

Most if not all CDNs have some terrible misbehavior (MS, Akamai, Limelight) 
where they send excessive amounts of traffic for the receiving connection 
size without ever backing off.

I can never get the ISPs experiencing the issues to collect information at 
the same time the CDNs are willing to look into it.

Could be something else, though.
