Root Level Technology is a relatively new company with a business model focused on acquiring customers instead of spending the time to build a client base. Root Level Technology has been the center of attention this year with the recent acquisitions of the FTNHosting brands (URPad, K-Disk, VMPort) and SemoWeb, which are prominent LE* providers. In addition they have acquired hosts from other markets as well, such as ReliaBox, ServerSavior, HostAndStore, and DediFrance.
It looks like yet another company is being added to their profile today, according to their nameserver records. Envioushost.com is now hosted on Root Level's DNS servers, but the WHOIS does not appear to reflect Root Level Technology just yet. It's possible things are still in the finalizing stage.
Envioushost.com also owns SubVM.com, which I assume was also acquired by Root Level Technology.
Congrats to Envioushost I guess? But honestly, this is the first time I've heard of them.
