I believe Akamai are building, to a reasonable degree, an on-net backbone.

There's no need for speculation. Jared has already said in this thread that's
exactly what he was hired for.

This is lame. They should be able to view NAT translation tables or
better yet have some method of watching flows.

Hello,
which attack protocol are seeing? I suspect you're seeing DNS based
amplification or similar, in which case you can't really pinpoint the attack
source...
800Mbps is not a whole lot of traffic - does it cause any disruptions to you?
If the prefixes are not in use, I would suggest the

but, until nancy drew walks the attack back upstream step by step, you
really do not know it's coming from clodflare or gobble.

I'm going to take a guess that ahmed is:

I'm 100% sure that those words mean something to you.. but not
operating your network they don't mean
I'd note that: "what prefixes?" isn't answered here... like: "what is
the thing on your network which is being attacked?"

For short term relief, you might consider asking your upstream provider to
block the unused IPs in your network that are being attacked. It may not get
everything, but it could drop the volume considerably. Just be sure that the
provider blocks them silently, without sending “no route to host”
An additional 800 Mbps would severely constrain if not topple dozens if not
hundreds of ISPs I know.

Hello,
you're forgetting if that was to be amplification, the source addresses would
not be within Google or CloudFlare ranges (especially not CloudFlare, as they
are not running a vulnerable recursor, and merely authoritative nameservers),
the only possibility would be Google as in Google

We've observed a customer receiving relative low volume attacks in the last
week (so low they didn't trigger our alarms).
My working theory is that with the Dec 3rd release of Halo Reach for PC, there
are gamers

But, as others have pointed out, plenty to knock a single subscriber, shared
access link (DOCSIS, wireless, or even well loaded GPON), or even a small
regional

If people cared, they would have anti-spoofing filters in place. Most on this
list will agree that amplification attacks can be mitigated or at least
severely reduced by
