@mv does "channel" make any sense to you in this context? Maybe something to do with high availability or DRDB? "Informe al soporte de Nagios sobre el traspaso del canal, porque el sábado 6 de Enero se realizo traspaso de canal y se detuvieron también los servicios, adjunto evidencia" I've worked with this guy before and usually I get the gist of his English but in this case idk.
