I wouldn't expect one person with one camera to cause such a load, but popular, cheap internet cameras pull this crap all the time. I remember reading a story here about one company that hardcoded a particular IP address for their NTP bootstrapping in their firmware, with thousands of devices all across the world and no way to easily update them. Such a thing can easily happen with consumer routers and other networking equipment, generating a publicly accessible link for their user's convenience.

If I saw the Time Warner ASN send too many requests, my first thought wouldn't be to just block a huge ISP. Who knows what mihjt be causing these issues and what you could be breaking by interrupting service.

The Time Warner NOC wouldn't be able to completely fix the problem if the source of the issue is the firmware of a certain shitty IoT device. If someone emailed their NOC about some weird IP cams installed by their customers causing load on their servers, they could feel like that's a problem between icanhazip and the camera manufacturer, not something they can fix.

The author is quite tolerant of the obviously malicious behaviour others are attacking his servers with. I'd have taken more aggressive measures instead of scaling up capacities myself. Because the problem is volume and not necessarily anything complex, I'd wager that even a simple block could be quite expensive because that traffic and the associated retries will be going somewhere. Directing the traffic towards the last router in their ASN through DNS would be something I'd consider, making it the problem of the network operators.
