There are recaps of flight restrictions, e.g. French DGAC publishes maps and plain text files recapitulating areas, in addition of individual NOTAMS:

ICAO announced in 2015 the creation of a specific member-collaborative tool CZRI, conflict zones risk information (currently very poor).

There are also other initiatives, e.g. SafeAirspace with text summary and maps. "SafeAirspace is managed by Flight Service Bureau, with contributions from The Airline Cooperative (225 international airlines), OpsGroup (1500 members), International Ops Bulletin feedback (40,000 readers), and data from the German BMVI, the UK DFT, the FAA, DGAC France, ICAO, and EASA."
