Abstract: A running narrative from the moderator of comp.dcom.telecom following the 1988 Hinsdale IL central office fire, which disrupted local, long-distance, and mobile telephone service, as well as ATC for Chicago O;Hare International Airport (ORD).
Notes: This is the canonical example of how fault-tolerance (redundancy in the PSTN) does not insure resilience and survivability (due to lack of geographic diversity in this case).
