The storm Vardah affected most utilities in Chennai. Some restored the service fairly quickly while others took some time.
A leading broadband service provider was the worst affected as their services were all by overhead cables strung haphazardly over buildings, trees, and poles. In some places, services were not restored for over 5 weeks. Many thought that this was the end of the service provider. So this garland on rejected cables probably signifies a requiem for that company or for any service over overhead wires.
BTW, is there no law against tying unauthorized cables over electric poles, trees, or other public structures?
