Router Failure Grounds Entire United Fleet

Greece is in trouble. China is in trouble. Puerto Rico is in trouble. The New York Stock Exchange has been shut down over a “technical issue.” And United Airlines has halted all its flights:

United midday on Wednesday said that the grounding had been caused by a computer-network router that malfunctioned, which disrupted its passenger reservations system. That meant that many passengers couldn’t check in for their flights. The disruption affected some places more than others, but it covered the entire network, which was why United decided to ground its entire mainline and United Express fleet worldwide.

Yikes! The malfunction of a single router torpedoed United’s reservation system for an entire day? That must be a pretty delicate network they’re running there.
