...if you were only the recipient of these robocalls. For several days a few months ago I was the recipient of massive blowback from these calls. My number was one that a robocaller was programmed to spoof and I received dozens upon dozens of calls, some of them extremely angry. I finally ended up recording an explanatory message on my voice mail.

Funny google never saw a website for this supposed company and its 'datacenter,' it only appears as a listing in a couple online business directories with no real information. Nearly 50 customers out of service? As another poster suggested, I suspect this is one small potatoes colo/hosting reseller who had their rack of servers confiscated from a larger colo facility.

This is so last year:

"The problem with QOS flags is that the end-user can set them. There's nothing preventing me from marking every single packet I send as high-priority."

Not a problem at all. Routers generally can be configured to pass Class of Service bits as received or rewrite them appropriately to fit one of the ISP's standard QoS profiles.
