The application discloses a network fault root cause positioning method and operation and maintenance equipment, relates to the technical field of network fault positioning, and is used for improving the accuracy of network fault root cause positioning.In the method, the operation and maintenance equipment constructs an elastic backtracking window associated with a network topology delay, combines a time-space alignment drift degree to quantify a cause-effect relationship, establishes a more reasonable log searching interval for each candidate root cause node, reduces time axis out-of-range time sequence misplacement of a preset window range, avoids a situation that related technology is difficult to capture the correlation between the two, and improves the accuracy of network fault root cause positioning.
