I have three locality domains, all with different registrars in Oregon. Two are with unique delegated locality domain registrars (think old school consultancies or ISPs that still exist) and one directly via localitymanagement.us (GoDaddy/USTLD).
One of the registrars is from an out of state operator that has been dead for three years. I tracked his widow down and had a number of cordial conversations over about 18 months. I've helped his widow renew some personal domains but she's recently told me that she's going to stop paying the hosting bill of the locality registrar and it'll shut down June 1st. I've offered to take over hosting, we'll see if she is convinced.
Several other locality users will likely also see their domains disappear once that happens as the USTLD registrar will require a notarized letter from the city/county of that domain to approve any "new" (new in their system) domains. Not easy for any mid or large sized city in the US.
I love locality domains clearly, but the bureaucracy applied since the start has piled up over the years.
I do worry that this poor Seattle ISP is going to get DDoS'ed by outsider (find an appropriate locality please if you go down this route) due to the popularity of this article, though!
RIP Jon.
