If communication links have insufficient capacity or their performance is no longer sufficient as a consequence of technical failures or denial-of-service (DoS) attacks, the communication of clients with servers will be restricted, for example. This will increase the time it takes to access internal and external services. As a result, it may only be possible to use such services to a limited extent (if at all). Business-relevant information may also no longer be available, which can bring essential business processes or entire production processes to a standstill.
