For the Telstra customers in Queensland, Australia, they found out the real reason very quickly as to why service was disrupted for a period of time. In the land down under, the wet weather conditions of late have been causing frogs in the local area in Childers, Queensland to breed “like crazy.” And apparently, one of them somehow managed to slip itself through a cabinet, pass some air filters, and eventually into one of the main boards of a Remote Integrated Multiplexer (RIM) unit.
Unfortunately, the frog's actions not only shorted out the unit, thus causing a disruption of service to 160 customers, but it had a lethal impact on the frog as well. For those affected customers, they were unable to place any incoming calls and even caused certain ISDN services to be “completely offline.”
