Tier 1 and why look at the URL to judge the ISP? When I ran my ISP I quickly deduced that outsourcing the web hosting and email was a good idea. Getting rid of those headaches gave me time to provide good service and bandwidth.
Jenny is a T2 provider AFAIK, they lease from whoever available, but mostly DFA Fibre. They franchise out the sales side to dealers, so most people only saw theae 3rd party agents.
Network providers build onto the Jenny network, but do not control it at all.
Rolf Stucky, of the Newcastle Stucky Motors group, runs Jenny Internet.
Any other info needed about Jenny that's publicly available and won't get me into trouble?
