The ranges again are
52.165.84.32/28
52.165.84.16/28
20.81.235.112/28
20.81.235.96/28
Anyone from AT&T that I can contact to escalate this block, as it's
affecting customers.

There has been an absolute tsunami of scriddie activity from some of
those ranges in past few days, along with large chunks of linode space.
We are blocking them outright, so I'd say AT&T's blocking would be more
than justified, hell, I'm not even in the same country as AT&T and
seeing it.
Strangely though, 99% of linodes crap is via IPv6, but Microsoft's
ranges are IPv4.
