These changes are disrupting the mechanisms that ensured the reliability of the North American electricity grid . In order to provide specific accuracy and reliability requirements , NTP requires configuration engineering specific to each time server and client site . Moreover , writing server extensions is tricky ( since they should not impact reliability or scalability ) and server specific . Wireless carriers are known for their low bandwidth , high latency , and unpre-dictable reliability .
