See also: Outage

CIMM DEFINITION: A natural or man made occurrence that can cause a gap or lapse in the signal or in data / video transmission. Often unexpected, can vary in time and length.

2: A period of time in which no data was collected by a provider due to environmental conditions including fire, power outages or system failures. (Source: Nielsen)

NOTE – Set-Top Box data collection often consists of a chain of transmission steps, from collection engine on the STB to collection server to aggregation servers and ultimately to the processors of the data, with possible hops through load balancers and proxy servers along the way. At each step in the transmission chain, either the server/computer or the network may fail. To provide avoid any gaps or data outage, multi-tier fault tolerance mechanism must be deployed including sufficient data caching at every error-detecting link in the transmission chain.
