The system proved to be unreliable in such a way that the safety of both firemen and civilians couldn’t be guaranteed. Instead the Dutch Fire Department will revert to analog communication instead, according to newspaper De Telegraaf (link, in Dutch)
Ditching C2000 is a very sensitive matter, especially political. Until now the Dutch government has turned its head when confronted with technical problems and ever increasing costs.
In the USA digital systems were dumped on numerous occasions in favor for an analog system. The best known example is Desert Sky, a localized version of the OpenSky system, once used by the Las Vegas Police Department. The reliability of the system was such that one police officer told a journalist that two tin cans and string might work better.
Admitting failure isn’t really in Dutch politician’s genes, so I’m pretty sure that they will blame anything, anybody and everything. C2000 is here to stay.
