This big international airport has a huge computerized central control system that’s maintained by an on-site field engineer — with help from the vendor half a world away.
“The software engineers relied heavily on the knowledge and expertise of the field engineer to install our software on the running system,” says a support pilot fish working for the vendor.
One day, the field engineer calls the vendor to say that the system’s BitBus device — which relays data between a network of sensors and the central control server — has a bug in its software.
According to the engineer, the BitBus device runs fine for a day or two. But then it begins “jabbering” — spewing corrupted messages onto the network — and has to be reset.
