Hello again everyone!
I am beginning to switch the server provider from Heroku to subaverage.site. The reason for the switch is mostly financial. FortunateMaps does not require that many computational resources, so you will not feel a difference between the two providers.
An onsite redirect to the new server has already been implemented, however, the fortunate-maps heroku server will be guaranteed to remain up and maintained until 03MAY2024.
The new link for FortunateMaps: https://fortunatemaps.subaverage.site
