Actually Hottboiinnc is not a former employee of DSLX, its how the company appeared to be operating when other people have been posting similar issues. And as far as Frontier/AT&T, AT&T covers far more than AT&T so T was suggested.
DSLX is still outsourced regardless, first level or higher. Also the company's MAIN and primary service is NOT retail HSI, DSLX is owned and operated 100% by a wholesale company, dialupusa.com/Ikano. Their business is wholesale, not retail.
And by operating as a wholesale company, yes, they have outsourced their network to Ikano, Especially when a wholesale ISP is not required to have a network, only a RADIUS server that is tied into the "ATM cloud" to AT&T or Frontier. There is nothing else to do besides a connection to the Internet.
DSLX also charges a surcharge on the bottom line to hide rate hikes. That when questioned, they blame on AT&T as passing it on to them or that AT&T charges it as well, which is not true.
