Noop. As I said, Microsuck at one point was sending to a 1.5Mbps
customer at nearly 25Mbps. Confirmed single machine. I believe it was
all the same source address, but like 20 separate streams.
Happened to a guy on Saturday as well. Yet another 1.5Mbps 900MHz
customer. Single PC directly to the radio. I was torching him and saw
about 12Mbps coming from MS's 13.x. Then it would settle for a while and
pick right back up again from LLNW at 6-8Mbps.
That guy opened a ticket and said he was getting less than 100kbps
download speed and no web pages would load. He responded about an hour
later and said everything was normal.
And yet another customer on Wednesday on PMP450 at 12Mbps tier was being
sent over 30Mbps.

Were all CDNs sending way more than the pipe size or only LimeLight?
Someone at Akamai sent out this message last week regarding a general
increase in usage:
=====
There were two major software updates that spanned Tuesday and
Wednesday which are responsible for the increase you saw.

I forgot about this. Yes. A little later in the day, I started to see
a lot of 13.n.n.n sources. Microsoft. Yeah, update Tuesday. Then the
same customer would start receiving from LLNW. Then Akamai. And back
to MS again. So it looks like they're *still* distributing updates
across various CDNs. And believe me, it's not like they were all
hitting this customer at once. One single CDN would try to send at
5-10X the customer's downlink MIR. Sometimes more. At one point I saw
over 20Mbps for 5-10 minutes. I saw pretty much the same thing with
about 15 other customers that I looked at. And they were spread across
5-6 towers. Some directly licensed fed, others farther towards the edge.
DDoS. CDN. Same thing. Or gorilla tactics at the very least. If the
customer calls and says "none of my other shit works, your internet
sucks" what are we supposed to do? Oh OK, here, we'll turn you up to
12Mbps and see what that does. Yeah screw that because now the CDN is
sending at 40Mbps! They need to stop fucking with TCP already! And no,
it doesn't matter where I put the policing/shaping. They still eat up
bandwidth on our upstreams. Like you said before Ken, yeah, it just
moves the problem somewhere else.

George, did you identify the application or content provider, or
only the CDN?
I think I started getting hit with the same thing early yesterday
afternoon. At first I thought I was getting DDOS attacks.

Yup. LLNW.

I assume you torched the traffic and verified it is all coming
from a particular CDN, not a random bunch of IPs as would be
the case with BT. Since this isn’t your first rodeo.

Because they dick with TCP.

And why is it the fault of the CDN? It could be a
customer with a 100-peer bittorrent session downloading
30GB of Ubuntu DVD ISOs.

I have had it with these CDNs sending more traffic
than the last mile can handle. Got a customer at
1.5Mbps on 900 FSK and they're sending to her at
15Mbps. Of course the AP reports RF downlink overloaded.
