Concerning ISP's I hear talk on here that it takes 5 psa's to be safe, at our hub they are saying it is 3, my state has not flipped yet, which is it ? If it truly is only 3, my hub won't get rid of a single contractor. I hear the goal is to get an entire hub with about 12 contractors, we would still have 3 times that many. Am I missing something here ? They stopped contractors from buying just one route about 1-2 years ago.
