Dakota says they have a "super fast DS3 backbone" and on the
phone their sales people have said they "are the backbone."
Reality includes a T-1 to Alternet, and an Ethernet drop from
ACSI. GTWINC uses Dakotacom to spam the net, and I've heard
that there are others (access) who are now joining their group.
Dakota does not use or understand BGP, are shunned by local
providers and interconnects, and uses two non-redundant net
blocks -- one from Alter over that link, and one from ACSI
over that link.
You'll note they switched their dns to use the Alter net
blocks. A quick traceroute to gtwinc shows they're still
there too:

They do not respond to email, do not read this list, do not
peer with anyone, and provide service to spammers.
All information correct to the best of my knowledge, ads in the
yellow pages, stuff said on the phone, and public information.
