The stations deployed on the Eastern flank are part of the Raspberry Shake initiative. The data can be visualized at https://stationview.raspberryshake.org/.
Moreover, the data are integrated in the data base EDUMED (French): http://edumed.unice.fr/.
For example, a day at the RFB1A (vertical component), at Fiumeffredo, looks like this :

The data are also available on the FDSN servers : it is possible to download it, and then visualize them using Obspy on Python.
NB : There are many reasons while a station can become off-line : no internet, technical problem… An annual maintenance makes sure to provide long-term record. So don’t worry of you can’t see some of the seismic stations 🙂
