data.umweltprofis.at: iCal service retired
I had to change the interval in my data.umweltprofis.at waste schedule when I noticed that the server throws an error when requesting a new iCal link at https://data.umweltprofis.at/opendata/AppointmentService/index.aspx

I contacted their support and they told me that this service is not going to be fixed because they are currently working on (another?) app.

Should this integration be marked as broken for the time being? Existing iCal URLs continue to work, at least for the time being.
