On this page, I collect and store information about lit buildings and metro fiber providers primarily based in the US (I'd do other countries if the information were as easily found). To be on this list, a company must as part of their business hook up buildings or wireless towers to metro fiber rings and either sell services directly to companies in those buildings or sell dark fiber to those that do, and usually in competition with the local ILEC. Any man-made structure that acts as a traffic aggregation point qualifies, and the services provided at it may be lit or dark. With no further ado:
There are obviously different business models, geographies, and who knows what. Therefore, this list is not meant to be a race, in fact few of these companies compete directly against each other and all compete against the ILEC primarily. It is just a list showing the general sense of the industry and where each company might fit in it. This information is updated, but infrequently - currently twice a year in June and December. If you see a company or information that ought to be here or just have a suggestion as to how to improve this page, send me an email at firstname.lastname@example.org.
