Hi,
it uses Pelias geocoder behind the scenes and we didn’t update the DB in a while. In fact, I’m finally doing it again, as there’s been a lot of improvements to the project lately, which will ensure, that we can regularly run new imports.
As for the frontend implementation: it’s hard to debug for us. We have to rely on Pelias doing its thing correctly and can’t respond to single problems. However, please check back next week, when a new build is implemented.
