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: 11 tucson-az-1-a12-0.acsi.net (206.222.97.8) [AS 6467] 112 msec 116 msec 128 ms ec 12 dakotacom.net.tucson-az-1.acsi.net (206.222.101.238) [AS 6467] 116 msec 116 msec 156 msec ... 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. Ehud
I've been receiving buckets of spam from dakotacom.net, as many as 90 per day. They've been connected to ACSI for many months.
ACSI has a new anti-spam AUP that went into effect today. Today I see that traceroutes to Dakotacom go through Alternet and medic-net-gw.customer.ALTER.NET. But the route looks odd, maybe a leak rather than a new real route.
I don't speak BGP (my multi-homed ISP does that for me), so can anyone see who's announcing 207.201.204.0/255.255.252.0 ? ACSI? Alternet? Both?
