Where possible, all links are to metro fiber maps offered on the website of the company operating the fiber. I prefer such links, but will sometimes host the files myself where the operator agrees, and in rare cases may point to third party maps. Where available, links to on-net building lists are also given.
Additional maps of metro fiber networks that ought to be on this list are very welcome, as are corrections to the above map links. Please just leave a comment below or send an email to firstname.lastname@example.org.
